This document discusses group communication. It begins by stating that RPC only allows communication between two parties, whereas sometimes multiple processes need to communicate with each other, which RPC cannot handle. An example given is a group of file servers cooperating to provide a fault-tolerant file service. The document then defines group communication as one-to-many communication, and notes that groups are dynamic - new groups can form and old groups can disband, and processes can join or leave groups. The purpose of group communication is to allow processes to interact with collections of other processes as a single entity.

Ch8 small group communication power pointms451711 This document defines and describes small group communication. Small group communication involves interaction between 3 to 9 people working interdependently. There are two main types of small groups: assigned groups where members are appointed, and emergent groups that are self-formed. A group develops a unique culture over time through norms, roles, and climate. Norms are the rules that guide behavior, roles are patterns of interaction either formal/positional or informal/behavioral, and climate is the emotional atmosphere created by trust, support, and cohesiveness among members. However, high cohesiveness can lead to "groupthink" where critical analysis is replaced with agreement at the expense of effective decision making.

Distributed Shared Memory on Ericsson Labs
Distributed Shared Memory on Ericsson LabsEricsson Labs The document describes Distributed Shared Memory (DSM), a technology that enables a distributed in-memory database for JavaScript applications. DSM allows multiple clients to access and modify the same data simultaneously. It resolves merge conflicts automatically and notifies clients of data changes. Developers can focus on building interactive web collaboration software without dealing with networking, databases, or concurrency issues. DSM supports both persistent storage and transient data sharing across clients in real-time.
Distributed Shared Memory Systems
Distributed Shared Memory SystemsAnkit Gupta Distributed shared memory (DSM) systems implement a shared memory model in distributed systems without physical shared memory. DSM provides a virtual shared address space between nodes. It overcomes high communication costs by moving data to the location of access. DSM research aims to build less expensive and larger parallel machines while eliminating programming difficulties of other architectures. DSM models include object, variable, page, and hardware-based approaches. Key issues in developing DSM involve granularity, memory coherence, replacement strategies, and avoiding thrashing. Common DSM algorithms are central server, migration, read replication, and full replication models.
Multicast
MulticastSagar Surve 1. The document discusses IP multicast routing protocols including DVMRP and PIM. It describes how multicast routing differs from unicast routing in establishing distribution trees from sources to receivers.
2. Key aspects covered include IGMP for hosts to join multicast groups, source trees versus shared trees, dense and sparse mode protocols, and data distribution policies using ACK and NACK approaches.
3. DVMRP is introduced as an early multicast routing protocol that uses distance vector exchange and reverse path forwarding to construct source trees and prune branches without receivers.
Distributed shred memory architecture
Distributed shred memory architectureMaulik Togadiya Distributed shared memory (DSM) is a memory architecture where physically separate memories can be addressed as a single logical address space. In a DSM system, data moves between nodes' main and secondary memories when a process accesses shared data. Each node has a memory mapping manager that maps the shared virtual memory to local physical memory. DSM provides advantages like shielding programmers from message passing, lower cost than multiprocessors, and large virtual address spaces, but disadvantages include potential performance penalties from remote data access and lack of programmer control over messaging.
Importance of group communication 
Importance of group communication kathan patel The document discusses group discussion and its importance. It defines a group as a collection of people gathered to perform a specific task, and defines discussion as the process of talking about something to reach a decision or exchange ideas. It then lists several benefits of group discussion, including understanding subjects more deeply, improving critical thinking, problem-solving skills, decision-making, hearing other ideas, improving listening skills, increasing confidence, and potentially changing attitudes.
Dsm (Distributed computing)
Dsm (Distributed computing)Sri Prasanna The document summarizes distributed shared memory (DSM), which allows networked computers to share a region of virtual memory in a way that appears local. The key points are:
1) DSM uses physical memory on each node to cache pages of shared virtual address space, making it appear like local memory to processes.
2) On a page fault, a DSM protocol is used to retrieve the requested page from the remote node holding it.
3) Simple designs have a single node hold each page or use a centralized directory, but these can become bottlenecks. Distributed directories and replication improve performance.
4) Consistency models define when modifications are visible, from strict sequential consistency to more relaxed models like release consistency.
Distributed shared memory shyam soni
Distributed shared memory shyam soniShyam Soni Distributed shared memory (DSM) allows nodes in a cluster to access shared memory across the cluster in addition to each node's private memory. DSM uses a software memory manager on each node to map local memory into a virtual shared memory space. It consists of nodes connected by high-speed communication and each node contains components associated with the DSM system. Algorithms for implementing DSM deal with distributing shared data across nodes to minimize access latency while maintaining data coherence with minimal overhead.

message passing vs shared memory
message passing vs shared memoryHamza Zahid This document compares message passing and shared memory architectures for parallel computing. It defines message passing as processors communicating through sending and receiving messages without a global memory, while shared memory allows processors to communicate through a shared virtual address space. The key difference is that message passing uses explicit communication through messages, while shared memory uses implicit communication through memory operations. It also discusses how the programming model and hardware architecture can be separated, with message passing able to support shared memory and vice versa.

Distributed Operating System_4Dr Sandeep Kumar Poonia A distributed system consists of multiple connected CPUs that appear as a single system to users. Distributed systems provide advantages like communication, resource sharing, reliability and scalability. However, they require distribution-aware software and uninterrupted network connectivity. Distributed operating systems manage resources across connected computers transparently. They provide various forms of transparency and handle issues like failure, concurrency and replication. Remote procedure calls allow calling remote services like local procedures to achieve transparency.
distributed shared memory
distributed shared memoryAshish Kumar Distributed shared memory (DSM) provides processes with a shared address space across distributed memory systems. DSM exists only virtually through primitives like read and write operations. It gives the illusion of physically shared memory while allowing loosely coupled distributed systems to share memory. DSM refers to applying this shared memory paradigm using distributed memory systems connected by a communication network. Each node has CPUs, memory, and blocks of shared memory can be cached locally but migrated on demand between nodes to maintain consistency.

INTERPERSONAL AND COMMUNICATION SKILLS- C.8Brenda Rachel Marie The document discusses different types of small group communication according to Cragan and Wright (1999). It describes descriptive groups like decision-making groups, social groups, study groups, and work groups. It also covers prescriptive groups such as colloquiums, forums, symposiums, and panels. Finally, it outlines different communication network patterns in small groups including wheel, circle, linear, and star networks.
What is a Group?
What is a Group?Bryan Agustin Oculam Groups are units composed of two or more people who interact for a purpose. There are several types of groups including formal groups created by an organization, informal groups formed without a specific purpose, primary groups with close regular interaction, and secondary groups with less interaction.
Group dynamics refer to the behaviors and psychological processes within and between groups. Norms are established beliefs and behaviors groups enforce on members. Cohesiveness is the degree group members are attracted to each other and motivated to remain part of the group, determined by factors like similarity, time spent together, isolation, threats, size, and rewards.
Reference groups are people or groups used for comparison to form values, attitudes or behaviors. Consumer-related reference groups include friendship
group communication and group discussion
group communication and group discussionswidan 1455 Group communication involves interaction between 3-20 people to exchange messages and potentially influence each other. It has components like interdependence on each other, being context-specific, dynamic over time as members learn, needing shared goals and norms, and providing feedback. Types of group communication include verbal discussion, technology-driven collaboration, non-verbal cues, in-person interaction, and virtual meetings. Group discussions aim to arrive at a conclusion through members' participation on a planned topic, and have advantages like diverse perspectives but also challenges like uneven participation.
Bjmc i, cm, unit-i, group communication
Bjmc i, cm, unit-i, group communicationRai University Groups consist of two or more people who interact together according to shared rules and goals. There are different types of groups including primary groups like families that involve close interaction, and secondary groups like workplaces that are less intimate but goal-oriented. People join groups for reasons like task accomplishment through group synergy, interpersonal support, and fulfilling social needs. Communicating effectively in groups can be challenging as it requires constructive participation, leadership, managing conflicts productively, and addressing issues like cohesion, group size, power structures, and norms. While groups have strengths like greater resources and thoroughness, they also have limitations such as time requirements and potential for conformity pressures.

Group dynamism
Group dynamismSUDIPTA PAUL A group is defined as two or more people who interact, share a common identity and goals, and have mutual rights and obligations. Key characteristics of groups include face-to-face interaction, interdependence, and self-identification as group members. Group dynamics examines how groups form and function through interactions between members. Groups typically progress through stages of forming, storming, norming, performing, and adjourning as they develop. Factors like group size, roles, norms, cohesiveness, tasks, and member resources influence a group's behavior and success.

Solution
.1. A collection of individuals who have regular contact and frequent interaction, mutual
influence, common feeling fcamaraderie, and who work together to achieve a common set of
goals.
2. Formal Groups- Formal groups are created and maintained to fulfill needs or tasks which arc
related to the total organisation mission. Thus these are consciously and deliberately created.
Such groups may be either permanent in the form of top management team such as board of
directors or management committees, work units in the various departments of the organisation,
staff groups providing specialised services to the organisation, and so on; or the formal groups
may be constituted on temporary basis for fulfilling certain specified objectives. When such
objectives are fulfilled they disappear. These may be in the form of temporary committee, task
force, etc. The working of formal groups is regulated by organisational rules and regulations.
Informals Group- Informal groups, on the other hand, are created in the organisation becausc of
operation of social and psychological forces operating at the work-place. Members create such
groups for their own satisfaction and their working is not regulated by the general framework of
organisational rules and regulations. Thus formal and informal organisations differ from each
other in the following respects:
1. Origin—As discussed above, reasons and circumstances of origin of both formal and informal
organisations are quite different. The formal groups are created deliberately and consciously in
the organisation by the framers of the organisation. On the other hand, informal groups arc
created because
of the operation of socio-psychological forces at the workplace, that is, people while working
together develop certain liking and disliking for others for the type of interactions not provided
officially.
2. Purpose—Since formal groups are deliberate creation, they are created for achieving the
legitimate objectives of the organisation. In fact, formal groups are basic product of formal
ogranisation structure. The informal groups are created by organisational members for their
social and psychological satisfaction. Thus they serve the purpose of organisational members

foundationsofgroupperformance-220420234649 (1).pdfSherwinEvangelista4 This document discusses five key factors that influence group performance: composition, size, norms, cohesiveness, and informal leadership. It describes how homogeneous and heterogeneous group compositions affect performance depending on task complexity. Group size impacts performance, with smaller groups generally performing better due to easier interaction and communication. Norms guide member behavior and expectations to increase productivity. Cohesiveness, defined as commitment to the group, generally improves performance. Informal leadership from elected members also contributes to group functioning.

Foundations of Group Performance.pptxLocal Government Unit of Candoni There are literally hundreds of definitions of the term group. Groups have been defined in terms of perceptions, motivation, organization, interdependencies, interactions, and myriad other elements. We will simply define a group as two or more persons who interact with one another such that each person influences and is influenced by each other person.
Group dynamics
Group dynamicsTanoj Patidar Curt Lewin was the creator of the term "group dynamics", which is the study of groups and group processes. Group dynamics deals with the attitudes, behaviors, and interactions within and between groups. It examines how groups are formed, their structures, and the processes that govern their functioning. Key aspects of group dynamics include roles, norms, cohesion, size, and diversity.
Work teams and group
Work teams and groupcymark09 This document discusses groups and teamwork. It defines groups as two or more people interacting to achieve objectives. Groups are classified as either formal, structured by an organization, or informal, formed spontaneously. Formal groups include command, task, interest, and friendship groups. People form groups to satisfy needs, proximity, goals, economics, and attraction. Effective groups progress through forming, storming, norming, performing, and adjourning stages. Key roles in groups include knowledge contribution, process observation, and leadership. Groups offer advantages like diverse ideas and support, but also disadvantages like slower decisions and potential lack of accountability. Techniques for group decision making are discussed, including interacting groups, brainstorming, nominal groups, and electronic

Unit 7Riyaj Shah The document discusses different types of groups that exist in organizations. It defines formal groups as designated work groups defined by an organization's structure to carry out work. Informal groups evolve to meet social or affiliation needs. The five stages of group development are forming, storming, norming, performing, and adjourning. Group structure includes elements like leadership, roles, norms, status, size, and composition. Techniques for group decision making include brainstorming, nominal group technique, Delphi technique, and devil's advocacy. Factors that contribute to team effectiveness are motivating tasks, clear goals, rewards, blending of skills, agreed upon norms, and problem-solving techniques.

It describes key concepts in group dynamics including formal vs informal groups, task vs social leadership roles, and influences of group size and composition. Techniques for structured group decision making are explored, such as brainstorming, nominal groups, Delphi groups, and dialectic decision methods. Potential benefits of group decisions are mentioned along with some weaknesses, including that meetings can be slow, expensive, and prone to "groupthink" where conformity overrides critical thinking.
Formation of groups
Formation of groupsUzma Abbas Shirazi This document discusses techniques for preparing social groups. It begins by defining social group work and outlining factors to consider when forming groups such as establishing a clear purpose, considering members' perspectives, and ensuring group composition allows for homogeneity. The document then discusses additional considerations like whether the group will be open or closed, optimal group size, meeting frequency and duration, and formulating group guidelines. It emphasizes the importance of preliminary individual meetings with prospective members to provide information, promote motivation, ensure needs are being met, allow for individualization, and give people choice.

Structural Response of Reinforced Self-Compacting Concrete Deep Beam Using Fi...
Structural Response of Reinforced Self-Compacting Concrete Deep Beam Using Fi...Journal of Soft Computing in Civil Engineering Analysis of reinforced concrete deep beam is based on simplified approximate method due to the complexity of the exact analysis. The complexity is due to a number of parameters affecting its response. To evaluate some of this parameters, finite element study of the structural behavior of the reinforced self-compacting concrete deep beam was carried out using Abaqus finite element modeling tool. The model was validated against experimental data from the literature. The parametric effects of varied concrete compressive strength, vertical web reinforcement ratio and horizontal web reinforcement ratio on the beam were tested on eight (8) different specimens under four points loads. The results of the validation work showed good agreement with the experimental studies. The parametric study revealed that the concrete compressive strength most significantly influenced the specimens’ response with the average of 41.1% and 49 % increment in the diagonal cracking and ultimate load respectively due to doubling of concrete compressive strength. Although the increase in horizontal web reinforcement ratio from 0.31 % to 0.63 % lead to average of 6.24 % increment on the diagonal cracking load, it does not influence the ultimate strength and the load-deflection response of the beams. Similar variation in vertical web reinforcement ratio leads to an average of 2.4 % and 15 % increment in cracking and ultimate load respectively with no appreciable effect on the load-deflection response.
ADVXAI IN MALWARE ANALYSIS FRAMEWORK: BALANCING EXPLAINABILITY WITH SECURITY
ADVXAI IN MALWARE ANALYSIS FRAMEWORK: BALANCING EXPLAINABILITY WITH SECURITYijscai With the increased use of Artificial Intelligence (AI) in malware analysis there is also an increased need to
understand the decisions models make when identifying malicious artifacts. Explainable AI (XAI) becomes
the answer to interpreting the decision-making process that AI malware analysis models use to determine
malicious benign samples to gain trust that in a production environment, the system is able to catch
malware. With any cyber innovation brings a new set of challenges and literature soon came out about XAI
as a new attack vector. Adversarial XAI (AdvXAI) is a relatively new concept but with AI applications in
many sectors, it is crucial to quickly respond to the attack surface that it creates. This paper seeks to
conceptualize a theoretical framework focused on addressing AdvXAI in malware analysis in an effort to
balance explainability with security. Following this framework, designing a machine with an AI malware
detection and analysis model will ensure that it can effectively analyze malware, explain how it came to its
decision, and be built securely to avoid adversarial attacks and manipulations. The framework focuses on
choosing malware datasets to train the model, choosing the AI model, choosing an XAI technique,
implementing AdvXAI defensive measures, and continually evaluating the model. This framework will
significantly contribute to automated malware detection and XAI efforts allowing for secure systems that
are resilient to adversarial attacks.

Group communication
- 1. Introduction to Group Communication RPC involves only two parties, the client and server. Sometimes we need multiple processes to communication among each others. RPC cannot handle this. For example, a group of file servers co-operating to offer a single, fault tolerant file service. Group Communication: one-to-many other than one-to-one communication Groups are dynamic: New groups can be created and old groups can be destroyed. A process can join a group or leave one. A process can be a member of several groups at the same time. The purpose of introducing groups is to allow processes to deal with collections of processes as a single abstraction. Thus, a process can send a message to a group of servers without having to know how many there are or where they are.
- 2. Meaning and Definition of Group A group consists of two or more persons who interact with each other, consciously for the achievement of certain common objectives. The members of the group are inter-dependent and are aware that they are part of a group.
- 3. Characteristics of a Group Social Interaction Stable Structure Common Interest Perceive Themselves as Part of Group
- 4. Social Interaction:One of the most obvious characteristics of group is. In other words, the members of group must have influthat they are composed of two or more people in social interactionence on each other.The interaction between parties may either verbal on non-verbal, but the parties must have some impact on each other to be considered as a group. Stable Structure:Group also must posses a stable structure. Although groups can change, and often do, there must be some stable relationships that keep group members together and functioning as an unit. Common Interest:The formulation of a group is closely related to some common goals or purpose. The achievement of common goals of a group is a matter of common concern for every member and they have an obligation to contribute for attaining the common goals. Perceive Themselves as Part of Group:Finally, to be a group, the individuals involved must perceive themselves as a group. Group is composed of people who recognize each other as a member of their group and can distinguish these individuals from non-members.
- 5. Importance of Group Communication 1. Wide Knowledge: 2. Diversity of Views 3. Acceptance 4. Legitimacy
- 6. 1) Wide Knowledge: Groups permit to pool more detailed information and knowledge. They constitute crucial impulse for sound decision-making. The aggregation of ideas of several individuals helps to make quality and sound decision. 2) Diversity of Views: There is no scope in group deliberations for any homogeneity of ideas. Groups permit not only more knowledge and information as input but it can bring heterogeneity in the decision-making process. Several alternatives can be considered and the best possible solutions can be arrived at. 3) Acceptance: In addition to heterogeneity to the decision-making group, decisions are accepted for implementation. Increased acceptance of solution is possible, people concerned with the decisions will be more likely to accept it and encourage others. There is a support and backing for group decision. 4) Legitimacy: In a democratic set-up, group decisions are based on the principles of democracy. Group decisions are more consistent with democratic ideas. These are therefore, legitimate than decisions made by a single person. A single person’s decision is known for its autocracy and arbitrariness.
