The analysis of possibilities of application of the small waterplane area twin hull ships (SWATH) as a specialty (universal) platform is performed. It is shown that the design of the specialized platform with a small waterplane area twin hull is characterized by a large number of parameters to be determined. The optimum relation selection between SWATH dimensions, seaworthiness, cost and efficiency is proposed by solving a multidimensional optimization problem with the use of special methods of searching solutions. The optimization problem of designing a universal platform is formulated. The constraints accounting on SWATH technical characteristics is produced by using the method of penalty functions. To solve the optimization problem, one of modern search methods – genetic algorithm is used. An example of solving the problem of selection the main dimensions of 25 m platform using a genetic algorithm is presented.

The article presents the results of research devoted to the further development of methods, models and algorithms for recognizing cyber threats, as well as the most common classes of cyber attacks and anomalies in critical computer systems (CCS). It is shown that the cyber security process for CCS controlled and analyzed by the values of several parameters of anomalies or signs of cyber attacks. This, in turn, makes it possible to carry out a preliminary assessment of information security with the help of two-stage recognition procedure in which initially used the methodology of adaptive regression splines for the processing of statistical data on the anomalies and cyber incidents in CCS, and then in the second stage are used designed logical recognition procedures based on the signs of matrix surfaces. This minimizes the number of training samples for the detection of objects in the framework, the relevant classes of cyber threats, attacks and anomalies.
The research on minimizing the amount of training samples of recognizing signs were performed. It is shown that for the recognition of objects within the known class of cyber threats, attacks and anomalies in the use of training facilities matrices used for training a representative set of long 3-5 attributes will allow to achieve maximum efficiency of the algorithm, reaching up to 98%.
Using the proposed method and models has allowed to reduce the amount of required object recognition rules within the class of 2.5-10 times, compared to the widely used in anomaly detection systems and methods of cyber attacks sequential sorting features and statistical algorithms states.

Model transformation is the cornerstone of Model-Driven Engineering (MDE) as it is crucial in Computer Aided Software Engineering (CASE) towards Object Oriented Analysis and Design (OOAD) and Object Oriented Programming (OOP). It also plays vital role in entity relationship model. Therefore it is indispensable to be treated as traditional software artefacts and assess quality of model transformations. Model-to-model transformations are from Platform Independent Model (PIM I) to Platform Independent Model (PIM II) and from PIM to Platform Specific Model (PSM). The goal of our research in this paper is to make these model transformations measurable. However, it is confined to proposing a set of metrics pertaining to consistency checking. The quality of transformations is measured in terms of consistency. The metrics proposed in this paper are general and can be reused. We evaluate the metrics using our framework named Extensible Real Time Software Design Inconsistency Checker (XRTSDIC) which supports end-to-end transformations of object oriented models. Our empirical study revealed that the proposed metrics add value to our model consistency checker as they quality in model transformations.

The Word Sense Disambiguation for Hindi Language is one of the biggest challenges faced by Natural Language Processing. In this paper we discuss issues in reducing ambiguity in Word Sense Disambiguation for Hindi Language. The concepts are induced in two modules Parsing and Word Sense Disambiguation for Hindi Language. Parsing is an extension of our previous work on shallow parser method that creates groups word which are essential for Machine Translation. Monolingual Hindi and English corpora are used. Following this we used machine learning technique such as supervised approach, unsupervised approach and domain specific sense with the help of Knowledge based methods. Knowledge based method uses Hindi and English WordNet tools. Supervised method is used to disambiguate the multiple tags in the context label with the correct tag. Unsupervised method is used to update the sentence with the correct sense and parts of speech tag. There are various websites which provide the facility of translation of Hindi language to English language such as Google Translator and Babefish Translator but these translators fail to resolve polysemy words in Hindi sentences the result is discussed in this paper. The accuracy result of part of speech tagging generated by our system is 92.09%. The accuracy results generated by our system for Chunk are window-3, window 2 and window1 are: 94.45%, 81.23%, and 81.11% respectively. We modify and develop Lesk algorithm which uses WordNet tools for Word Sense Disambiguation. We compare the system's performance with the website Google Translator. We also examine errors made by Google Translator for given input Hindi sentence. Our system generates correct translation with Word Sense Disambiguation for given input Hindi sentence as shown in the Figure12.

Most business process Companies are interested for new solutions and techniques in organisations. Relating to the big data to achieve that business process must be reengineered. Reengineering of business process can be done based on six sigma activities like Define, Measure, Analyze, Improve, Control and Report. In Business Process Reengineering, the two constants of any organisation are people and process If individuals are motivated and working hard, here the business process are compressive and organisational process will be poor and posses high failure rate. In order to overcome these effects Business Process Reengineering must have some assessing capabilities which is referred as Desired Organizational Capabilities (DOC) and total quality management (TQM) to increasing the efficiency of reengineering and makes the manufacturing of logistical systems more scientific.

School of Information Engineering, Nanchang Hangkong University, 696 Fenghe South Ave., Nanchang, China, 330063

Evaluation of mobility model is an important means to ensure the quality and design level. At present, many mobility models are proposed for opportunistic networks. But, there is no practical quantitative evaluation system to evaluate the mobility models. Firstly, this paper put forward a comprehensive evaluation index system of mobility model based on the analysis of the main factors affecting the quality of mobility model and the relationship between them. Secondly, based on the theory of fuzzy comprehensive evaluation, this paper put forward a fuzzy comprehensive evaluation model for mobility model (FCEM). In this model, the membership function of fuzzy mathematics is used to deal with the fuzzy evaluation of each index of the mobility model. The model realizes the quantitative evaluation of mobility model. This model not only provides new ideas and methods for mobility model evaluation, but also provides help and guarantee for mobile node modelling. Finally, the application of the model is demonstrated through the evaluation of the random waypoint (RWP) model.

Enhance detecting and preventing scheme for ARP Poisoning using DHCP PDF

Vidya Srivastava, Dayashankar Singh

M. Tech Student. Deptt. Of CSE MMMUT, Gorakhpur (UP), India

The client which is using LAN for mapping network address connected to its corresponding MAC address is done by Address Resolution Protocol, which is a primary protocol. It is well known that ARP is determined and works properly in case there is no malignant client in the network but in practical scenario it is not possible. The primary motive of an attacker is always tried to find a strategy which is further accomplished to launch various attacks. ARP gives this accountability – the unsubstantiated and stateless characteristics of the protocol which accredit the attacker to conduct biggest level attacks. In this paper, an attempt is made to resolve out or minimize the attempt of attacker by providing a validation using DHCP server. By the introduction of DHCP (Dynamic host control protocol) such that if an attacker applies the IP of host not in network can be prohibited. The simulation result has been shown in the dissertation report. By the response of DHCP correct matching of IP and MAC could only respond and thus poisoning can be detected and protected successfully.
