It is discussed in many studies and demonstrated in the many researches that based on certain applications, analog design of filter has several issues including complex design, re-use Limitations, and accuracy of generating the output at various frequencies. Therefore, instead of analog filter design the digital design of the filter is preferred for both Finite and Infinite Impulse Response Filter. This paper demonstrates the design of the digital FIR filter designed is demonstrated using ultrascale Field Programming Gate Array. The filter is designed using Coefficient multiplier via Canonic Signed Digit – CSD Technique. The optimized design of digital filter is carried out via real-time implementation is performed using Ultra Scale FPGA. The filter is designed and tested with ordinary filter at 10 MHz and 10 GHz frequencies. The performance analysis of the system is illustrated using the response rate at the bit stream of 16 bit. In the results, it is demonstrated that for 10 MHz frequency design FIR filter in FPGA the 30% faster response filter is achieved at for 10 GHz, the 15% faster response is achieved at the IO Standard of LVCOMS. The proposed Improved Finite Impulse Response Filter Design using Ultra Scale FPGA helps in increasing design performance to increase the speed of overall response of FIR filter that is lacking in ordinary Filters.

A need for constant health monitoring system is essential especially for heart diseases which may cause sudden stroke and death. We present in this paper the design and development of a low cost, efficient and user-friendly ECG monitoring device. Most of the heart rate measurement devices and tools available are quite expensive and may not be easily available in some areas. Presented device monitors the patient’s body information using three lead silver chloride ECG disposable electrodes and detects the pulse signal. The detected heart pulse signal is first filtered and then amplified. The device displays the heart signal on a MATLAB graphical user interface while simultaneously showing the digitized pulse rate on a digital LCD. The device was tested on female patients aged 20-24. The results obtained were reliable compared with electrocardiogram reports and similar available devices of much higher development cost.

Outcome-based-education (OBE) is an educational theory that bases each part of an educational system around goals (outcomes). Pakistan Engineering Council (PEC) introduced the OBE in Pakistani engineering higher-education-institutions (HEIs),from 2018, in the replacement of previously followed Syllabus& Curriculum based education system. Key to success of OBE System is its continuous-quality-improvement (CQI) mechanism. The CQI mechanism design should be based on accurate assessment process and flawless evaluation of OBE System parameters; otherwise the OBE System’s benefits cannot be achieved. However, some HEIs have not devised an effective CQI mechanism and they still using classical procedures and academic tools in implementation of the OBE Framework, which cannot give desired results from the new System. This paper presents that; instead of presently employed loose-control, a modified stringent control strategy for academic activity and employment of latest technology, can make the CQI mechanism, more effective and efficient. This paper therefore presents a two-fold contribution. At first, the implementation problems of the OBE System are critically analyzed. Secondly, few modifications in the existing approaches have been introduced to achieve the desired results from the recently adopted OBE system.

Stroke is a medical condition that is the fifth cause of death and a leading cause of disability. The different reasons for stroke are high B.P, obesity, smoking, etc. recovery can only be sped up by regular physiotherapy and willpower of the patient. Regular physiotherapy can be interrupted by other commitments of the patient or by the doctor's unavailability. This may lead to a delay in the recovery process. Therefore, the efforts are needed to tackle the problem. The proposed device can be used to monitor and carry out selected exercises advised by the doctor. Here the upper right limb is our focus because it is the most common area to be affected. Furthermore, android application is also designed which have different consoles for doctor and patient. The patient’s app shows the history and progress of the patient while the doctor sets the time and can also see the progress.

Expansive soils are generally considered problematic due to undesirable geotechnical characteristics like expansion, shrinking, settlement, and heaving. Such soils have low shear strength which decreases after wetting or other physical aggravations. Subsequently, such soils need proper improvement before constructing a structure on them. Different industrial wastes have been used for the stabilization of weak soil in the past. In the current investigation, the impact of waste glass powder (WGP) on the strength and swelling characteristic of swelling soils have been assessed. The primary target of this examination was to research the utilization of waste glass powder in geotechnical applications for controlling the settlement and expanding qualities. For this reason, the local expansive soil of district Karak, Pakistan was selected and their engineering properties were assessed. The experimental work consists of conducting the consistency limits, California bearing ratio (CBR), specific gravity standard Procter tests. The mentioned tests were carried out on both natural as well as modified specimens. For modification purposes, waste glass powder (WGP) was added in different proportions with the incremental rate of 4%, for instant 0%, 4%, 8%, 12%, 16%, and 20%. The addition of waste glass powder greatly reduced the swelling properties of the tested soil and also improved the engineering characteristics. A maximum reduction in swelling was observed at 20% addition of waste glass powder. Similarly, the liquid limid also reduced, and the specific gravity and maximum dry density increased at optimum glass powder content.
