Mobile ad hoc networks allow to create very dynamic communication systems, which are independent from any fixed infrastructure. One of the most important issues regarding the management of an ad hoc network is the configuration of the system according to the way users move. Since a centralized control structure does not exist, we need to determine how the IP addresses must be assigned to the nodes in the network. In this paper we add a security mechanism to VASM protocol based on zero knowledge approach. A hash function has very low running time. So this so this scheme is very light-weight. The VASM protocol uses coordinate value of point in main address sheet for generating addresses. The performances of this solution are evaluated through the Behavioral simulation, which allowed us to check the correctness of the protocol and to estimate the control traffic generated under different operating conditions.

While Bookmark and Screen-memo memorize Web pages for future re-visit, re-visiting Web pages by using Bookmark or Screen-memo still requires a large amount of operation for cellular-phone users since the screen sizes of cellular phones are generally much smaller than the sizes of Web pages. In this paper, we describe the design and implementation of a content clipping system for Web browsing using cellular phones. This system presents multiple candidates for clipping a content, then, mobile users can easily specify the clipped target. Moreover, this system semi-automatically generates tags attached to the contents and automatically classifies the clipped contents. By using this system, users can easily specify contents of interest in Web pages and re-visit them with simple operations.

Pharmaceutical and healthcare industries are highly regulated industries in each and every nation around the globe. Every nation has a governing body like USFDA, TGA, and M.H.R.A, Schedule-M etc. that assures that the medicines are manufactured under strict guidelines to ensure highest quality of manufactured products. However assuring high quality products requires that the manufacturing facility is monitored 24x7 and this monitoring requires the use of high end networking technology. Currently pharmaceutical plants capture this information using a number of scalar sensors that measure temperature, pressure, humidity etc. In some developing nations this sensed information is manually recorded by a supervisor in charge. This often results in data entry errors that need to be addressed. This paper aims at identifying current technologies that can be used by Indian Pharmaceutical Industries to capture this information and process it in real time to provide the kind of track and trace which so far is not implemented in majority of Indian pharmaceutical companies. We specifically focus on identifying the importance of Wireless Sensor Networks and how it can be implemented in pharmaceutical manufacturing plants.

A Cellular Neural Network (CNN) is a neural network model in which cells are linked only to neighboring cells. In image processing, a CNN can be used for noise reduction and edge detection. Small-World Cellular Neural Networks (SWCNN) are CNNs extended by adding a small-world link, which is a global short-cut. Although SWCNNs have better performance than CNNs, one of the weaknesses of the SWCNN is fault tolerance. Previously, we proposed multiple SWCNN layers to improve the fault tolerance of the SWCNN. However, as this only addresses termination failures it is not sufficient. In this paper, we propose a Time Stamp Voting method to improve tolerance of intermittent faults. This method is superior to Triple Modular Redundancy (TMR).

We investigate the mapping of OWL-S process models to ISPL - the system description language for MCMAS, a symbolic model checker tailored to the verification of multi agent systems. In our approach, services are viewed as agents, and service compositions as multi agent systems. We show how various composition constructs defined in OWL-S can be encoded into ISPL by using the proposed mapping rules. We use an extended version of the BravoAir process model from the OWL-S suite of examples to illustrate the technique.

Many people, young or old, adult or children live with life-threatening health conditions and deal with frequent visits to the doctor's office or a healthcare facility for blood tests. Blood tests are one of the key processes that aid in examining people's health. Although people with certain illness can check certain blood properties at home without professional help, most people require going to a place where their blood may be analyzed in a laboratory environment to examine the state of their illness. Frequent visitation to a medical clinic for blood tests is exhausting and expensive. This periodical process leads the patients to being depressed and, over time, careless about their health. In this study, we introduce a wireless system, Non-Invasive Real-Time Blood Observation System (NIRT-BOS). NIRT-BOS will be able to read blood properties via body sensors and report the results online and, depending on the patient’s wishes, off line. NIRT-BOS will offer continuous blood data collection capabilities with the ability to detect a problem and signal a warning in real time. We are developing NIRT-BOS based on life experiences of people with chronic illnesses such as Diabetes, Heart, Kidney or Liver Diseases. The main purpose of this study is to help the frequent visitation struggles of people who live with certain health conditions and, most importantly, to be able to give them a sense of security, independence, and, to some degree, give them the peace of mind which comes from being free from the worry of their illnesses.

Actin is a cytoskeletal protein found in all eukaryotic cells. It is involved in cellular motility and cytokinesis and is essential for processes such as defense against microorganisms and for cancer cells to spread as metastases. Actin binds ATP in physiological conditions and hydrolyzes it to ADP after polymerizing into microfilaments. ADF/cofilin is one of the key actin-binding proteins and is required for the rapid actin turnover necessary in cell motility. It functions by taking advantage of the ATP/ADP gradient in actin filaments by associating with the older parts of actin filaments to depolymerize filaments by binding with 100 fold higher affinity to ADP-actin than to ATP-actin. ADF/cofilin also binds monomeric ADP-actin more strongly than ATP-actin and inhibits nucleotide exchange. However, the structural mechanisms for these processes are a mystery as a crystal structure is not available for the actin-cofilin complex. Yet, ADF/cofilin binds actin through an ADF homology (ADF-H) domain, which is also found in other actin-binding proteins, such as twinfilin, and a structure of the complex of ATP-actin with the C-terminal ADF-H domain of twinfilin was recently determined. We are using the crystal structure of the actin-Twf-C complex to simulate the interaction of ADF/cofilin with ADP-actin and ATP-actin through molecular dynamics simulations and to examine conformational changes that may explain the mechanisms for ADF/cofilin inhibition of nucleotide exchange as well as the stronger affinity for ADP-actin. Thus far we have run a 2 ns simulation of the Twf-C-actin complex with ATP. Surprisingly, in this simulation the adenine ring of ATP underwent a large ring flip even though in simulations of monomeric ATP-actin the ATP is extremely stable. This result was unexpected since a similar ring flip was previously seen in ADP-Arp3 (actin-related protein 3), but in this case the nucleotide was being released. Experimentally, however, ADF/cofilin prevents nucleotide release. It may be possible that the ATP is actually going into a more stable conformation. We are working on running the simulation for a longer time as well as replacing ADP into the complex. Analyzing ADF/cofilin’s contributions to cell motility through computational biology may help us understand its roles in apoptosis and several diseases, such as Alzheimer’s and cancer.

We show in this paper that the metabolic chain can be supposed a potential-Hamiltonian system in which the dynamical flow can be shared between gradient dissipative and periodic conservative parts. If the chain is branched and if we know the fluxes at the extremities of each branch we can deduce information about the internal kinetics (e.g. place of allosteric and Michaelian step with respect to those of branching paths, cooperatively) from minimal additional measurements inside the black box constituted by the system. We will treat as example the glycolysis with the pentose pathway whose fluxes measurements are done at the pyruvate and pentose levels.

Digital Ecosystem is defined as “an open, loosely coupled, domain clustered, demand-driven, self-organizing and agent-based environment, in which each species is proactive and responsive for its own benefit and profit” [1]. Species in the Digital Ecosystem can play dual roles, which are service requester (client) service provider (server). A service provider enters the Digital Ecosystem by publishing a service metadata in the service factory, in which the service metadata can be clustered by domain-specific ontologies provided by the Digital Ecosystem. Two issues emerge here. First of all, vast and heterogeneous service metadata are ubiquitous before the Digital Ecosystem technology emerges. It is a challenge for the Digital Ecosystem to organize these metadata. In order to solve this issue, an automatic service metadata clustering approach could be desired. However, this could educe the second issue – the automatic association between service concepts and service metadata could not agree with service providers’ perceptions, as a result of the differences among individual understandings. To solve the two issues, in this paper, we present a hybrid ontology-based metadata clustering methodology comprising an extended case-based reasoning algorithm-based automatic concept-metadata association approach and a service provider-oriented concept-metadata association approach.

The advances in the area of mobile computing is likely to make it feasible to predict the availability of wireless networks and their application level Quality of Service (QoS) characteristics along the user mobility path. Such predictions are referred to as QoS predictions which are provided by the QoS Context Source (QoSCS) hosted in the fixed network. On the multi-homed mobile devices, the QoS Predictions could be used for the handover to the optimal wireless network which satisfies the QoS requirements of the mobile applications. However, to achieve this functionality, a middleware support is necessary to obtain and make use of QoS predictions in real-time. To this end, we present design, architecture and validation of the context-aware computing support for network-assisted seamless vertical handover that uses QoS predictions to take a handover decision. We evaluate the proposed solution, in a case where it is applied in the mobile health care applications. The obtained simulation results encourage us to conduct the real-time system validation by employing the proposed solution.
