MPC is an optimal control technique and has become a wide-spread solution in numerous industrial applications due to its constraints handling ability. However, MPC requires high computational time to compute the control signal because it uses the state space model of the system in optimization process and thus it suits to regulate the slow dynamic processes i-e petrochemical, fluid catalic cracking, temperature control etc. Therefore, in recent years researchers have proposed number of methods i-e Laguerre Functions based, Scale Reduction technique etc to reduce computational burden of conventional MPC and improve its feasibility for fast dynamic systems. In this research work computational comparison between MPC and Scale Reduction based MPC for a fast dynamic system i-e speed control of a DC motor in presence of hard constraints is presented. The simulations are done by first developing the state space model of DC motor and then simulating it in MATLAB. The results have been investigated in two modes. In first mode speed of DC motor is controlled by both techniques in absence of hard constraints and in second mode hard constraints are applied. The results have shown that Scale Reduction technique improves computational efficiency of MPC and make it feasible for the regulation of fast dynamic systems.

A healthy individual maintains an optimum core body temperature of 37 degree Celsius. If the cold environment of the individual accelerates, the condition of hypothermia can develop. Hypothermia is one of the major hindrances faced by winter athletes. Initially the symptoms include rapid heart rate and breathing rate, but if condition of Hypothermia gets prolonged it can lead to slower heart and breathing rate and eventually results in unconsciousness and heart failure. Commercially available jackets have temperature settings but are manual and do not serve the purpose of hypothermia. The paper describes the design of a low-cost and very effective jacket that enables accurate measurement of core body temperature with the aid of a pyroelectric sensor incorporated in one of the circular parts of the earmuffs that the athlete is going to wear. If core body temperature of less than 37 degrees is detected, heating pads would get activated to attain optimal temperature. The jacket provides the ultimate solution to treat hypothermia only when the internal conditions exhibit that you actually have it and not due to the external environmental conditions. The prototype was found to detect and treat hypothermia effectively.

in recent times, the Internet of Things (IoT) is pre-eminent to our survival and is emerging as the technology of choice for the public as well as private sectors. IoT based health management system will provide effective communication between patient and physician to cure the patient in time. The proposed system consists of a smart patient health tracking mechanism that uses different medical sensors (Body Temperature Sensor, Environment Humidity and Temperature Sensor, Heart Beat Sensor, and ECG) to track patients’ health, while using GPS (Global Positioning System) to inform the Ambulance Management and Physician about the basic and crucial health parameters of the patient. The data collected from sensors is also stored in a centralize cloud for further analysis of patient health. To get access to the stored information on the cloud, a graphical user interface is designed on a website. Moreover, LCDs and buzzers are used for real-time monitoring and indication of a patient’s health parameters.

Problem exists to effectively learn technical topics requiring sound mathematical practices. Especially in engineering domain, detailed mathematical illustrations sometimes robs the time of teaching which could be effectively used to make students learn to apply and explore the applications in practice. In the subject of Signals and Systems continuous time convolution of signals is one such example. It is a mathematical operation involving shifting, folding of signals along with integration and differentiation. All these operations perplex many students. This becomes worse when students are already possessing mathematics learning and anxiety problems. Identifying this as a bottle neck in teaching convolution, this article is aimed to provide an alternate and simulation method for solving convolution integral in continuous time case. Quantitative analysis was also carried out on a case study to determine that the developed application helped students in better learning of the topic.

Among major demand areas, transport sector of Pakistan is responsible for approximately 30 Mt of CO2 emissions every year. Under Business as usual scenario, these emissions are expected to go beyond 70 Mt by 2040 which exceedingly defies the constraints applied by Kyoto Protocol and policy measures to control Climate Change. Hence, a paradigm shift is needed in transport sector of Pakistan which deviates it from the path of traditional fossil fuels to either next generation biofuels or mainly toward electric vehicles. However, due to technology and infrastructure lack, the status of electric vehicles in Pakistan is non-existent. Secondly, keeping in view the economic status of country, electric vehicles of first generation are not capable to travel large distances especially on the motorways of Pakistan that does not have any charging stations installed on them. This study performs a theoretical energy and environment assessment through installation of Piezo-electric materials on different pathways along the motorways of Pakistan. A complete feasibility and economic analysis are performed that shows the number of electric vehicles that can be charged, the energy and environmental savings (since electric vehicles have zero tail-end emissions), and the total cost for implementing the proposed system. In coherence with the developed countries and their adaption of electric vehicles, the results obtained showed a positive impact under the scenario that the price of piezoelectric materials will continue to decrease with the same pace for at least next 5 years. Considering the current cost of crystals, the system will take approximately 20 years to payback which is approximately equal to their life spans. However, the economic value taking into account the environmental benefits, the system is rendered feasible.

Rehabilitation treatment is the process which helps people to restore their functioning. Nowadays poor body posture and forward neck problem has become a greater issue all around the world. At home or in the workplace, everyday activities such as force and repetition can play a part in causing these problems. Many people have this postural abnormality, which is most common in aging, working, and old-aged groups. For this, a low-price, reliable, and precise system for in-home rehabilitation is required. In this paper, the device for an in-home rehabilitation is designed for patients especially outpatients (who can’t visit daily or afford a personal trainer) for correcting their improper postures by giving visual feedback of postural data in real-time using LabVIEW software. Our system analyzes the patient’s whole-body posture by extracting the human skeleton called skeleton tracking which gives positional information for the 20 prime skeleton’s joint points that make up the human body using a Kinect sensor. We designed the Pattern Recognition Neural Network algorithm using MATLAB script function in LabVIEW to examine the tracked human skeleton. To verify that the posture is accurate or not, we have collected the data about 896 samples of exercising postures for both conditions to train the network. We performed 70% training, 15% validation and 15% testing of the network which results in classifying the right class of postures. Further testing will also be done.

Local clock synchronization of nodes is one of the most critical problems with Time-Division Multiple Access (TDMA)-based protocols for dissemination of warning messages in Vehicular Ad hoc Networks (VANETs). Unsynchronized nodes’ clocks make time slot reservations inefficient, which results in channel collisions at a large scale. In this paper, we propose a novel cluster-based Vehicle-to-Vehicle Local Clock Synchronization (VLCS) technique, which is composed of two phases to synchronize all nodes in a VANET to a commonly shared clock. The first phase performs inter-cluster clock synchronization, whereas the second phase accomplishes intra-cluster clock synchronization where each member node synchronizes its clock with the corresponding cluster head. Simulation results demonstrate significant improvement of VLCS over an eminent VANETs clock synchronization technique.
