The presence of change in any production process, especially in software development, is usually intolerant and highly resistive as it creates confusions among developers and breaks the confidence of customers resulting in non-reliable production. Change is inevitable especially while software is built. There could be several reasons for such confusions likely deployment of the application on multiple variant platforms or having multiple releases, or distinct support tools for simultaneous testing, or developers with deputation over multiple projects at the same time, or following bad or weak practices of undertaking frequent modifications over any certified post-release. Such confusions are indeed needed to be managed in a highly organized manner with recording the traces in the case for the post inspective backpropagation for quick determination of any error causing the software failure. Business ventures are operating in a highly competitive arena globally, where such practices are extremely risky and annoying. Software configuration management, SCM fulfils the objective to avoid such confusions when change is requested, where keeping maximum trace record of development i.e. software traceability highly help to determine the timely error for correction without any hassle. In this paper, we have tried best to give awareness to all software development stakeholders understanding trouble of change, maintaining traceability with a quality focus, where practices of change and configuration management are explored.

Multipliers are key components of many high performance systems such as microprocessors, digital signal processors, etc. Optimizing the speed and area of the multiplier is major design issue which is usually conflicting constraint so that improving speed results mostly in bigger areas. A VHDL designed architecture based on booth multiplication algorithm is proposed which not only optimize speed but also efficient on energy use.

Change management or configuration management is becoming necessity for every facet of software system development. Traceability of objects i.e. artifacts or information units becomes core talent for authentic determination of the parametric information over the explicit instance of time. This paper presents the evolving and useful concept of traceability management wrapped in change management paradigm that provides perception for requirement analysis phase. We have analyzed the patient data requirements workflow model with respect to the traceability management process. We have proposed a new approach for better traceability of patient data management model (PDMM) for identification and realization of trace relationships within requirements (IRTRR) in healthcare environment. We have named the model as PDMM-IRTRR framework. The key activities represented in the proposed framework are also highlighted.

Classical relational model offer very little built-in support for managing time varying data. Relational model mainly deal with crisp data and not with imprecise data. Managing temporal data in the relational environment keeping the imprecise and fuzzy nature of the data requires the extension of the relational model. Small numbers of extended models at conceptual level are proposed and there is no significant implementation of such model exists. Importance of developing ontological framework for imprecise data and temporal data is required in many applications such as health and patient databases. In this paper we propose a temporal fuzzy ontology for patient data in a hospital environment. On the basis of the ontology defined we propose a conceptual fuzzy temporal relational model (FTRM) for handling time varying attributes and fuzzy attributes in the relational database environment. The proposed model is easy to define, manage and incorporates the important and relevant features in the target fuzzy temporal relational model.

Trapped ion transportation operations in the horizontal direction have been already demonstrated successfully by several researchers. In this paper, we propose a novel trap design for fast and adiabatic vertical shuttling of trapped ions. The novel planar surface electrode ion trap consists of a set of independently controlled small strip-electrodes of fixed widths. New trap geometry was modelled to support vertical shuttling protocols. Ion trajectory in the vertical direction from the surface of the trap was simulated for from ~40μm height to ~100μm. Trap-depth and secular frequencies were investigated during shuttling of ion with slow and fast shuttling protocols.

The pilotless, self-triggered and self-driven, autonomous, the computer programmed aerial vehicle commonly called as “Unmanned-Aerial-Vehicle”, UAV and generally known as “Drone” is one of the tremendous inventions of this century. This machine is not only small in size, but due to being a human-less, it is highly risk-free for humans as it is controlled remotely, however, work in the environment where human reach is difficult or impossible. The utilization of human brain waves to operate such a machine is an added technological advancement, which is the evolution of BCI, “Brain-Computer Interface”, that has provided the power of autonomous to this machine. This paper discusses the civil use of UAVs i.e. autonomous pilotless aerial vehicles, how they work, their characteristics, their structure and dynamics, their applications mostly commercial use etc. The concept of BCI (Brain-Computer Interface) with AI (Artificial Intelligence) to automate such machines with the computer as well...

This research presents a systematic analysis and proposed development on traffic management schemes based on Vehicle Activated Signs (VAS) using computing techniques. The literature revealed that the previous dynamic solutions provide results based on traffic congestion. However, they lacked to address weather conditions. Traffic management schemes and their limitations were analyzed. Different methods were found to effectively handle traffic load. An algorithm scheme has been proposed after analyzing past implemented systems, integrated the weather API with the system to make decisions based on both weather situation and traffic condition. The proposed solution makes decision based-on the current and average of previously gathered data i.e. previous traffic situation data and data gathered by a sensor network. It is concluded that an enhanced system based on star topology network integrated with the sensor networks may provide a more efficient solution to this problem.

This research presents a LASER locking scheme that provides considerably much higher stabilization of LASER frequency in real-time environment. The scheme is implemented using LabVIEW Software in Real-time Operating System (RTOS). The scheme allows stability of the LASERs within the line-width of the respective transitions. Using this scheme, the Extended Cavity Diode LASERs (ECDL) are locked to a saturated absorption curve of a reference LASER automatically. The system can remain locked for several hours. The scheme also provides a human friendly interface and allows access to tune the LASER frequencies.

Enhanced Dynamic Wedges are used in radiotherapy treatment to modify the dose distribution in target volume so that a de-sired dose distribution is achieved. The technique being highly advanced and computer controlled, requires enhanced degree of quality assurance. The investigation aimed to verify the constancy of treatment dose, when the orientation of the enhanced dy-namic wedge (EDW) is reversed. It has been noted that there is a slight change in the monitor units with the reversal of EDW orientation. The calculated dose for two opposite orientations of EDW has been compared for 6 and 10 MV photon beams, by two different calculation systems (Pencil Beam & Collapsed Cone) to assure the quality of EDW technique as well as to increase its reliability. The difference in the calculated dose for Y1-IN and Y2-OUT orientation, for three different field sizes and all seven wedge angels, is very small and hence not enough to change the wedge factor significantly.

Electricity calamity and scarcity is among one of the burning questions of third world countries especially in Pakistan these days. There exist multiple other ways to generate electrical energy. In order to address one of the innovative alternate method of electricity generation, we have worked on the technique to generate electricity i.e. using paddling impact. This is done by applying paddling force on floor which is converted to kinetic energy and then to mechanical energy, thereafter mechanical energy is further transformed into electrical energy which is accumulated for genuine use towards power hungry load. The phenomena works on the Law of Conservation of Energy. Undoubtedly this method cannot meet the total requirement of large number of consumers but this can handle energy crisis to some magnitude which seems tremendous and significant accomplishment. This electricity production is not only pollution free but it is more economical since it require low maintenance efforts and can minimize the ongoing burden of charging batteries for hand carrying electrical appliances and street lights etc. Although some engineers, researchers and companies have initiated to provide such solution but lot of work is needed to design for economical solution to be available to every consumer. In this paper we have presented the extended design and implementation.
