Hospital Information System (HIS) is a comprehensive, integrated information system designed to manage the administrative, clinical and support aspects of a hospital. It provides numerous advantages in patient care and hospital management. With the advancement in technology and cost effective solutions, HIS adoption among the hospitals has increased substantially in recent years. Various project management tools are available which helpful in effective planning and project monitoring. In spite of effective planning and implementation in phase manner, the concern remains regarding the challenges faced during implementation and usage of HIS. These challenges includes Technical Challenges like Security of Data, Unauthorized access, confidential information, integration of Medical Softwares to avoid duplicate entry and Administrative Challenges like involvement of stakeholders, user acceptance, lack of ownership etc. This can be subdued either by utilization of data entry operators or through offline and duplicate entries, but such implementation does not achieve the purpose of HIS. Apart from good project management, there are various other factors such as involvement of users, effective trainings, awareness program, secure and role based application, compliance to industry standards for easily integration with other applications etc., which increase success factor of implementation. This paper presents the challenges faced in implementation of HIS in super specialty hospital, Postgraduate Institute of Medical Education and Research, Chandigarh (PGIMER) and strategies adapted to overcome them. © 2014 IEEE.

Efficient broadcast in MANET using trust mechanisms

Efficient broadcast in MANET using trust mechanisms

Broadcasting is the fundamental operation of mobile ad hoc network, in which a source node transmits the packets that is disseminated to all the nodes in the network. Broadcasting is used in mobile ad hoc network either to broadcast control packets during route discovery or to broadcast the data packets. The simplest method used for broadcast is flooding that degenerates the performance of MANET due to packets collision, contention, and redundancy. This results in the wastage of limited network bandwidth. This paper proposes an efficient approach to broadcast with reduced redundancy and improved performance. The proposed approach is based on the determination of trust between the communicating nodes called as intimacy factor (IF). The IF is calculated for the entire route by the nodes, which is updated. The IF determines whether the packet is to be broadcast or not. The proposed approach reduces the control packet overhead by 40% without compromising the packet delivery ratio and maintaining it above 90%. It also reduces the end-to-end delay of the packets up to 60% and thus leads to the increase in average throughput.

With the ubiquity of new information technology and media, more effective and friendly methods for human computer interaction (HCI) are being developed. The first step for any intelligent HCI system is face detection and one of the most friendly HCI systems is facial expression recognition. Although Facial Expression Recognition for HCI introduces the frontiers of vision-based interfaces for intelligent human computer interaction, very little has been explored for capturing one or more expressions from mixed expressions which are a mixture of two closely related expressions. This paper presents the idea of improving the recognition accuracy of one or more of the six prototypic expressions namely happiness, surprise, fear, disgust, sadness and anger from the mixture of two facial expressions. For this purpose a motion gradient based optical flow for muscle movement is computed between frames of a given video sequence. The computed optical flow is further used to generate feature vector as the signature of six basic prototypic expressions. Decision Tree generated rule base is used for clustering the feature vectors obtained in the video sequence and the result of clustering is used for recognition of expressions. Manhattan distance metric is used which captures the relative intensity of expressions for a given face present in a frame. Based on the score of intensity of each expression, degree of presence of each of the six basic facial expressions has been determined. With the introduction of Component Based Analysis which is basically computing the feature vectors on the proposed regions of interest on a face, considerable improvement has been noticed regarding recognition of one or more expressions. The results have been validated against human judgement. © Springer International Publishing Switzerland 2014.

In control engineering, any system that takes some input signals, processes it and gives output signals, e.g. an electrical transformer, a mechanical lever, a car's hydraulic brake system, a country's economy, population of a country etc., can be treated like a black - box plant. Any given plant should be stable and also should perform well in terms of speed, accuracy and other properties. If it does not behave so, another system called controller is designed which is used in conjunction with the plant. In this paper, we propose an alternative, easy-to-use algebraic method to find the transfer function of the controller with better accuracy than graphical methods like root locus and bode plot. Our algorithm has complexity O(nˆ3). © 2010 Springer-Verlag Berlin Heidelberg.

This research and development on conversion co-processor presents an abstract- level hardware implementation of the conversion between various number formats for FPGAs in modular way. Replacing the floating point expressions with specialized integer or fixed point operations can greatly improve the system performance in several applications. The replacement requires several types of conversions from one format to another format. The proposed conversion co-processor accelerator can work in parallel with HOST machine to accept a large amount of input data and convert to another format and apply fixed point or integer arithmetic operations and the result is converted back to the floating point or fixed point format. The floating point conversions unit designs are fully compliant with the IEEE 754-2008 standard. The proposed system has been tested on Xilinx Virtex 6 xc6vlx550t-2ff1759 FPGA and achieves a throughput of 350MFLOPs per second. © 2015 IEEE.

Cyber forensics is the process of seizure, acquisition and analysis of digital evidence. development of cyber forensics tools is often challenging as more and more variations of digital devices are marketed rapidly and new cyber crime scenarios are reported frequently. If the team follows a traditional development method with a long planning phase, the product will be obsolete by the time it is released. So the product development teams should follow agile development methods that can ensure quick release and efficient change management. In this paper, we present the need to adopt agile methodology of project management in the development of Cyber Forensic Tools through a sample case study. © 2010 IEEE.

Security Enhancement in Data Encryption Standard

Security Enhancement in Data Encryption Standard

3rd International Conference on Information Systems, Technology and Management

Data Encryption Standard (DES) is the most widely used cryptosystem. Faster computers raised the need of high security cryptosystems. Due to its small key length and simple feistel network, many cryptanalysts developed various methods, like parallel and exhaustive attack, to break DES. DES is most vulnerable to differential cryptanalysis attack. This paper proposes modifications in DES to ensure security enhancement by improving the key length and the weak round function against cryptographic attacks. We show analytically that the modified DES is stronger against cryptographic attacks. The proposed modifications divide the expanded 48 bits of right block into two equal blocks of 24 bits. Then two different functions are performed on these two blocks. The effective key length is increased to 112 bits by using 2 keys. These two keys are used in special sequence with round numbers. The analysis shows that for the proposed approach, the probability of characteristic for differential cryptanalysis is reduced and the unicity distance is better as compared to standard DES.

Smart Rooms integrated with sensors, actuators, wireless networks and context-aware applications will soon become part of our daily life. To build successful context-aware systems, we must develop an architecture to reduce the difficulty and cost of building these systems. This paper presents the architecture of ChaturKartha, developed to setup a context aware intelligent Room. Based on the gathered contextual knowledge, ChaturKartha infer what the users expect and accordingly delivers the expected services. Our architecture explores the use of Semantic Web languages for defining context ontology and for reasoning over such information.
