In this paper, an inventory model for production of a singlearticle with anunevenmanufacturing rate and manufacturing time subsidiary selling cost has been considered. The considered production inventory model is accepted to create perfect items in beginning however because of different elements, after some time the production begins diminishing exponentially with time, i.e., the variable production rate has been thought of. The demand is time subordinate. Initially up to certain time, production rate remains constant. But after some time, due to various factors, production will decrease. Therefore, the efficiency (E) of such factors must be increased to get more production which can maintain the production efficiency cost which has been applied. Considering this fact inverse efficiency λ has been introduced in production rate.By utilizing differential calculus, expected maximumprofit has been resolved. The goal of the examination is to decide the ideal arrangement for a production framework that expands the total benefit subject to certain limitations viable. Results are examined by means of a mathematical example to outline the hypothesis.

Real-time Brain IoT Systems are costly. But, developing a cheaper system has been accelerated greatly by the better research that is being done on Virtual Brain. The death of an important person on a secret mission is consider sensitive information and must be handled with as much security as possible. By ensuring this discreteness, the time taken for the message of their death to reach the relevant authority is increased to up to a few days. The time taken to deliver the message is too much. These days, the improvements in hardware increasing the abilities of the Virtual brain and of the wearable Brain IoT sensors have made the development of numerous new software frameworks possible for the developers to create useful applications that combine the human brain with IoT. Multiple sensory pathways are also enabled for communications of the human brain with larger sized data.The main aim of this project is to upload confidential documents onto the clouds securely as possible. Knowledge on how every individual thinks and recalls memory is found by the Virtual cerebrum undertaking. Both of the mentioned fields have been accelerated greatly in terms of development by these researches. This will in turn drive the need of an energy-efficient technology that supports the wider demands of the IoT. The brain activity extraction in IoT has been surveyed thoroughly in this project. This includes IoT models based on Electroencephalogram (EEG), machine learning and the current active platforms. The main findings of our survey highlights three major trends of development in the virtual brain development system, viz, IoT, EEGand cloud computing.Since the human body has a the low frequency range of 7Hz or below 7Hz, it cannot be detected by the EEG sensor. So, the wearable EEG sensor has a band that goes around the head. Once the individual is dead, the confidential information that is securely stored in the cloud can be sent to the mail id that was preregistered by the user without any delay. This system is very time efficient.

Rising petroleum derivative costs and ecological contamination with their utilization have brought expanded worldwide interest in biodiesel creation and use. The journey for bio-energy in this manner has been supported all through the world to care for the climate and substitute bio-diesel with petroleum products. The goal is to assess the seed oil of cotton and to utilize it as an elective fuel. Cottonseed oil has diesel-like fuel properties. Cottonseed oil is blended in with diesel in various extents viz 5%, 10%, 15%, 20%, and 25% experimented in a compression ignition engine. Bio-diesel is generated from cottonseed through a compound interaction called transesterification. With the petrol energizes right now known and their expanding interest for utilization, it is expected that they won't keep going long. By examination, the exhibition attributes give off an impression of being improved with the utilization of cottonseed oil for brake power, CO, HC, NO and NOx emissions.

Background: Osteoarthritis is a highly prevalent musculoskeletal condition. A huge variety of treatment interventions are available but have shown success to limited extent. Treatment intervention managing the symptoms both at the periphery and at the central pain processing can be a better approach to the treat this condition. Objective: The present study aimed to see the time effect of the combination of Transcranial direct current stimulation (tDCS) and Transcutaneous electrical nerve stimulation (TENS) in knee OA patients. Study design: Prepost experimental study design. Methodology: Seventeen patients with chronic knee osteoarthritis as per American College of Rheumatology criteria were recruited in the study. The combination of tDCS and TENS was applied for 5 consecutive days over the most painful knee. The outcome measures were pain (VAS), function (six minute walk test), disability and quality of life (Knee injury and osteoarthritis outcome score) measured at the baseline, one week, two weeks and six weeks after the interventions. Data was analyzed using SPSS (version 21.0) software. Result: The result of the study showed significant improvement in pain, function and quality of life at the short term (week 1) as well as in long term (6 weeks) after the interventions. Conclusion: The combination of tDCS and TENS is a potential intervention in reducing pain and improving function both at short and long term in knee OA patients.

The objective of this work is to study the transient heat transfer behavior during precooling of cylindrical food product at different air flow rates. Temperature measurement is carried out at the center of the specimen at different air flow rates (3.8, 4.0, 4.2 & 4.5 m/s). These temperature distributions are plotted with time. The terms of Fourier equation were evaluated and thermal diffusivity was plotted against the temperature variation during cooling of the cylindrical food product.Surface film conductance values is also calculated in present work, at different air flow rates. These values are effective values, which included the additional cooling effect due to moisture evaporation from the exposed product surface. Variation of Reynolds number and Nusselt number is also plotted with different air velocities and it is found that more favorable results of thermal conductivity and thermal diffusivity is obtain at 3.8 m/s. Which ultimately saves energy and provide optimum cooling for the specimen at the given air velocity.
