What is .NET view state?

View state is the method that the ASP.NET page framework uses to preserve page and control values between round trips. When the HTML markup for the page is rendered, the current state of the page and values that must be retained during postback are serialized into base64-encoded strings.

What are the three main activities associated with the seal?

According to the domain expert, instances of the Dive concept are associated with three main activities: resting, traveling, foraging and a mixed activity traveling-foraging . Starting from our semantic trajectory ontology owlSemanticTrajectory ( Figure 6.4 ), we define the seal trajectory ontology, named owlSealTrajectory ( Figure 6.7 ).

How to select groups in Amiramol?

Furthermore, additional information, such as type and membership of the groups, can be displayed. Groups can be selected by being clicked on in the browser, by use of expressions, or through interaction within the viewer. Groups that were selected in the browser will also be highlighted in the viewer, and vice versa. Apart from selecting, the selection browser offers the possibility to hide arbitrary parts in all of the above-mentioned representations, so that the user can concentrate on particular regions of interest.

What are the three states of a seal?

We consider three main states of a seal: Haulout, Cruise and Dive. Figure 6.5 shows the three states, the transitions and their guard conditions. Every state is related to a seal’s activity, such as Resting, Traveling and Foraging. The captured data can also contain some meta-data called conductivity-temperature-depth ( CTD) about the marine environment such as water conductivity, temperature and pressure. From the analysis of the captured data, we define a seal’s trajectory model ( Figure 6.6 ).

Why is shape complementarity important?

Shape complementarity is an important aspect in molecular interactions. Shape properties are relevant for manual docking of ligands to proteins and for automated docking procedures. The characterization of molecular shapes is therefore very useful for molecular modeling.

What are the challenges of big data analysis?

For example, there are a few challenges as follows: (i) the data can be arbitrarily complex structures (eg, graph data) and cannot be efficiently stored in relational database; (ii) the data access of large-scale data processing are frequent and complex, result ing in inefficient disk I/O accesses or network communications; and (iii) last but not least, a variety of unpredictable failure problems must be tackled in the distributed environment, so the data processing system must have a fault tolerance mechanism to recovery the task computation automatically.

What is CLI domain?

A CLI application domain is contained within an operating system process. A process may contain many application domains. Application domains have isolation properties similar to that of operating system processes: Multiple threads can exist within a single application domain. An application within a domain can be stopped without affecting ...

What is a context bound object?

There is a third type of object called a context-bound object which can be marshalled by reference across domains and also within the context of its own application domain. Because of the verifiable type-safety of managed code, a CLI can provide fault isolation between domains at a much lower cost than an operating system process can.

What is application domain?

Application domains are a purely managed code concept. Any included native /unmanaged code (e.g., C++) is largely unaware of them. Static variables seem to be shared across domains, callbacks can be problematic, and any memory corruption bugs in one domain is likely to corrupt other domains.

What is a CLI?

In this sense, a CLI is like a mini-operating system. It runs a single process that contains a number of sub-processes, or application domains. The advantage of application domains is that running multiple application domains may require fewer resources, such as memory, than running multiple operating system processes.

Can a CLI communicate with an application domain?

Direct communication cannot be achieved across application domains. However, application domains can still talk to each other by passing objects via marshalling by value (unbound objects), marshalling by reference through a proxy (application-domain-bound objects). There is a third type of object called a context-bound object which can be marshalled by reference across domains and also within the context of its own application domain. Because of the verifiable type-safety of managed code, a CLI can provide fault isolation between domains at a much lower cost than an operating system process can. The static type verification used for isolation does not require the same process switches or hardware ring transitions that an operating system process requires.

Can multiple threads exist in a domain?

Multiple threads can exist within a single application domain. An application within a domain can be stopped without affecting the state of another domain in the same process. A fault or exception in one domain does not affect an application in another domain or crash the entire process that hosts the domains.

Is configuration information part of a domain's scope?

Configuration information is part of a domain's scope, not the scope of the process.

Why is CLR used in application domains?

The CLR provides fault isolation between application domains with less overhead than processes, due to its inherent feature of verifiable type-safety of managed code. Also, multiple threads can reside in an application domain, they are free to cross application domain boundaries.

What is context bound MBR?

Context-bound: MBR object used across domains or within the context of its own application domain.

What is the purpose of Marshal-By-Value?

To enable communication between objects in different application domains one of the following three types of objects is used: Marshal-By-Value: Complete copy of the object passed to the calling application domain. This is used when the state of object can be moved for performance reasons.

What is application security?

Application security by restricting the direct access to the code running in one application from the code or resources of another application.

What is optimal utilization of system resources?

Optimum utilization of system resources by using fewer processes to execute multiple applications.

What are the three platforms used in data fusion?from sciencedirect.com

The food product has been characterized by three analytical platforms: gas-chromatography/mass-spectrometry ( GC-MS); excitation-emission fluorescence (EEM) and near infrared spectroscopy (NIR). Three alternatives approaches are presented for data fusion: 1) structure revealing data fusion (ACMTF), top figure; 2) common components and specific weights analysis (ComDim), middle figure; distinctive and common simultaneous component analysis (DISCO), bottom figure. The factor matrix (scores) for the shared samples mode is represented on the right, the C labels indicate common components and the D labels the distinctive components. Going from left to the right the first set of common components (the first C on the left) is common to GC-MS and EEM, the second set to EEM and NIR and the third set to all the three data blocks. The first set of distinctive components (the first D on the left) is for GC-MS, the second for EEM and the third for NIR.

What is resource sharing?from sciencedirect.com

Resource sharing is a classic and effective approach to resource efficiency. As more and more Big Data applications with diversifying and heterogeneous resource requirements tend to deploy in the cloud [ 5, 6 ], there are vast opportunities for resource sharing [ 1, 7 ]. Recent work has shown that fine-grained and dynamic resource allocation techniques (eg, resource multiplexing or overcommitting [ 1, 8–11 ]) can significantly improve the resource utilization compared to T-shirt model [ 1 ]. As adding/removing resources is directly performed on the existing VMs, a fine-grained resource allocation is also known as a scale-up model, and the cost tends to much smaller compared to the scale-out model. Unfortunately, current IaaS clouds do not offer resource sharing among VMs, even if those VMs belong to the same tenant. Resource sharing models are needed for better cost efficiency of tenants and higher resource utilization of cloud providers.

Why is cloud computing important?from sciencedirect.com

Cloud computing has emerged as an appealing paradigm for Big Data processing over the Internet due to its cost effectiveness and powerful computational capacity. Current infrastructure-as-a-service (IaaS) clouds allow tenants to acquire and release resources in the form of virtual machines (VMs) on a pay-as-you-use basis. Most IaaS cloud providers such as Amazon EC2 offer a number of VM types (such as small, medium, large, and extra-large) with fixed amount of CPU, main memory, and disk. Tenants can only purchase fixed-size VMs and increase/decrease the number of VMs when the resource demands change. This is known as T-shirt and scale-out model [ 1 ]. However, the T-shirt model leads to inefficient allocation of cloud resources, which translates to higher capital expenses and operating costs for cloud providers, as well as an increase of monetary cost for tenants. First, the granularity of resource acquisition/release is coarse in the sense that the fix-sized VMs are not tailored for cloud applications with dynamic demands delicately. As a result, tenants need to overprovision resource (costly), or risk performance penalty and service level agreement (SLA) violations. Second, elastic resource scaling in clouds [ 2 ], also known as a scale-out model, is also costly due to the latencies involved in VM instantiating [ 3] and software runtime overhead [ 4 ]. These costs are ultimately borne by tenants in terms of monetary cost or performance penalty.

What is conformation analysis?from sciencedirect.com

Less frequently, they also undergo larger shape changes. Taken together, individual molecular configurations with similar shapes are called conformations. Conformation analysis is used to determine the essential shapes of molecules and the probabilities of transitions between these shapes. amiraMol offers an extensive set of tools for visual analysis of trajectories from molecular dynamics simulations. This allows users to determine representatives of conformations and to depict conformations [ 19 ]. In Fig. 38.9 (right), a representative molecular shape is displayed, together with the shape density of the corresponding conformation.

What is Amiramol used for?from sciencedirect.com

In addition to the previous techniques, amiraMol offers algorithms for generating triangular approximations of solvent-excluded and solvent-accessible surfaces [ 18 ]. Additionally, van der Waals surfaces and interfaces between arbitrary parts of a molecule or between different molecules can be computed. All triangular surfaces can be color-coded by arbitrary scalar fields.

What is a group in chemistry?from sciencedirect.com

What is an app domain?

It is an isolation layer provided by the .NET runtime. As such, App domains live with in a process (1 process can have many app domains) and have their own virtual address space.

What happens if you run 2 different appmains?

As to your specifics - if you run code in 2 different AppDomains within a process, the code will run in isolation. Any communication between the AppDomains will get either serialized or handled via MarshallByRefObject. It behaves very much like using remoting in this regard. This provides a huge amount of security - you can run code that you don't trust, and if it does something wrong, it will not affect you.

What is CS:IP in computer?

If you look at it from processor internal details perspective it sets different value for Code Segment (the CS) register. code and CS:IP (Instruction Pointer ) register is the one that is in execution by the processor.

What is the meaning of "back up"?

Making statements based on opinion; back them up with references or personal experience.

Is AppDomain a light weight process?

Each application running within a process, AppDomain is also a light-weight process or we can say logical unit which having group of assemblies (this is a container which contain group of assemblies ) and this exist inside of the process at isolation level of same process, this allows to run multiple assemblies within same process and prevent them for direct access.

Is an appdominant a process?

An easy way to think of it is almost like a lighter-weight process sitting inside of your main process. Each AppDomain exists within a process in complete isolation, which allows you to run code safely (it can be unloaded without tearing down the whole process if needed), with separate security, etc.

Can there be multiple threads in an app domain?

Could there be multiple threads in app domain. Technically yes as the CS value going to be in the current process. you can change IP to something else by a jump statement (function call/goto combination) can two threads in two different app domain communicate (No. refer point 1.)

Why is an app domain important?

An App Domain is relatively cheaper when compared to the process to create, and has relatively less overhead to maintain. Think about a server that hosts hundreds of applications. Before the app domain was introduced, each running application used to create one process.

What is an app domain?

App Domain is a logical container for code and data just like process and has separate memory space and access to resources. App domain also serves as a boundary like a process that does avoid any accidental or illegal attempts to access the data of an object in one running application from another.

Why is it important to run code in one application?

It is also necessary to ensure that code running in one application cannot adversely affect other, applications. When you run an application, Windows creates a process for the application with a specific process id and other attributes. Each process is allocated with necessary memory and a set of resources.

How many threads are there in a process?

Every Windows process contains at least one thread which takes care of the application execution. Processes can have many threads and they speed up execution and give more responsiveness but a process that contains a single primary thread of execution is considered to be more thread-safe.

What does "useshellexecute" mean?

StartInfo.UseShellExecute - help you specify whether to use the operating system shell to start the process or not. If you set UseShellExecute=True, the application will use the operating system shell to start processes. With OS shell, you can start any document (which is any registered file type associated with an executable that has a default open action) and perform operations on the file, such as printing, by using the Process object. If you set UseShellExecute to false, you can start only executables by using the Process object.

What is a process in Windows?

Process. A process is an operating system concept and it is the smallest unit of isolation provided by Windows OS. Each application or piece of code runs in Windows runs under the boundary of a process. Application isolation makes sure the failure of one process does not affect the functioning of another process.
