<p>In the current pandemic situation is arisen due to COVID-19, So every human has required to take precaution like wear mass, keep distancing, sanitizing hand, don't touch anything if not which not necessary. But something is like Table, door, vehicles etc. we touch so there is chance of spreading disease. In college and Offices, the peoples are meet so there are chances spreading disease due to the touching of door or any other thing on which germs are present. The project is based on automation, in which we will making an automatic opening and closing of door mechanism (home/college door). In which the door is open when the sensor on the door cut then mechanism is operated and open the door and after close automatically. So, there is no physical touch of human with door, hence it will help to prevent or reduce the spreading of pandemic disease COVID-19.<b> </b>Our project is based on Ultrasonic Sensor and Arduino, in which door is automatically opens and closes by detecting a person. As soon as a person approaches the door (at about 2 or 3 feet), the door automatically turned open and after some time (about 5 to 10 seconds), the door closes by turning in the reverse direction. Such Automatic Door Opening and closing systems are very useful as you do not need a person to standby the door and open it whenever a guest comes. Also, since the doors are opened and closed only when a person approaches the door, there is significantly less loss of air conditioning.</p>

The system of opening and closing the hotel room doors is already using RFID but its use is still not optimal because the card used is very expensive and the card used can only be one card for each room, so if the card is lost, you have to re-enter the card id. Therefore, digital electronic technology systems and devices are needed to make it easier to open the door and close the hotel room so that it can facilitate the hotel security system with automatic locks. This system and device uses an E-KTP and an Internet of Thing (IoT)-based Keypad and which functions to control the device using a NodeMCU while for a card reader with an RFID engine. The research method uses a model, namely with a prototype model for making systems and automatic room door locking system tools. The results and conclusions of the manufacture of hotel room automatic door locking systems and devices using an Internet of Thing (IoT)-based E-KTP equipped with a message LCD and keypad as a door opening solution if the RFID machine does not work. The security of hotel guests who stay is more guaranteed and can also make it easier for guests and hotel staff with an automatic hotel room door lock system. The results of the user's assessment of the work of a series of systems and tools to open and lock this automatic hotel room door are very good with a value of 88.7%.

In air conditioning and refrigeration (ACR) systems, the established industry method of capacity control is compressor ON/OFF cycling operations. This paper presents the design of load-predictive controller using compressor ON/OFF operations for temperature regulation with a target application of transport refrigeration systems. A dynamic ACR system model, which consists of a refrigerated cargo space, and a vapor compressor cycle (VCC) system, is developed. The validated VCC model is presented that captures compressor ON/OFF duty cycling dynamics. The dynamic cargo space model is described to accommodate varying conditions, such as door openings. The load-predictive controller tracks the pre-cool and predictive refrigeration load information which is generated based on the operating conditions in the next door-opening event, and decides to operate the VCC system with either normal ON/OFF control or pre-cool actions. Simulation results show that improved cargo space temperature regulation is obtained by implementing the load-predictive control strategy over the baseline industrial hysteretic control scheme in the coupled VCC/cargo space system.

Energy is an important aspect in our day to day life. It is important to save energy wherever possible that to electric energy. We are suffering from electric energy crisis now-a-days. In order to save electric energy alternate system is chosen and it is implemented which would save electric energy. Wasting energy for supplementary or supporting works like machine door opening and closing considered as uneconomical. Energy consuming system consumes lot of energy for supporting works. In this energy saving concept two different types of system can be coupled to work as a single system which would save much energy than before. Our concept discusses about the same. Energy wastage for operating CNC machine door is taken for consideration in our work and analysis has been done on it. A new hydraulic operating system is proposed to overcome the difficulties.

Routine Immunization Schedule

After the 2010 earthquake, Haiti committed to introducing 4 new antigens into its routine immunization schedule, which required improving its cold chain (ie, temperature-controlled supply chain) and increasing vaccine storage capacity by installing new refrigerators. We tested the feasibility of using remote temperature monitoring devices (RTMDs) in Haiti in a sample of vaccine refrigerators fueled by solar panels, propane gas, or electricity. We analyzed data from 16 RTMDs monitoring 24 refrigerators in 15 sites from March through August 2014. Although 5 of the 16 RTMDs exhibited intermittent data gaps, we identified typical temperature patterns consistent with refrigerator door opening and closing, propane depletion, thermostat insufficiency, and overstocking. Actual start-up, annual maintenance, and annual electricity costs for using RTMDs were $686, $179, and $9 per refrigerator, respectively. In Haiti, RTMD use was feasible. RTMDs could be prioritized for use with existing refrigerators with high volumes of vaccines and new refrigerators to certify their functionality before use. Vaccine vial monitors could provide additional useful information about cumulative heat exposure and possible vaccine denaturation.

Rhythmic patterns of compression and reinflation of the thin-walled hollow tubes of the insect tracheal system have been observed in a number of insects. These movements may be important for facilitating the transport and exchange of respiratory gases, but observing and characterizing the dynamics of internal physiological systems within live insects can be challenging due to their size and exoskeleton. Using synchrotron X-ray phase-contrast imaging, we observed dynamical behavior in the tracheal system of the beetle, Odontotaenius disjunctus. Similar to observations of tracheal compression in other insects, specific regions of tracheae in the thorax of O. disjunctus exhibit rhythmic collapse and reinflation. During tracheal compression, the opposing sides of a tracheal tube converge, causing the effective diameter of the tube to decrease. However, a unique characteristic of tracheal compression in this species is that certain tracheae collapse and reinflate with a wavelike motion. In the dorsal cephalic tracheae, compression begins anteriorly and continues until the tube is uniformly flattened; reinflation takes place in the reverse direction, starting with the posterior end of the tube and continuing until the tube is fully reinflated. We report the detailed kinematics of this pattern as well as additional observations that show tracheal compression coordinated with spiracle opening and closing. These findings suggest that tracheal compression may function to drive flow within the body, facilitating internal mixing of respiratory gases and ventilation of distal regions of the tracheal system.

Check valves are used to minimize flow reversal. In general, the two primary design objectives of installing a check valve in a system include quick opening in forward flow and fast closure in reverse flow. The fast response requirements in both opening and closing directions are challenging. In the opening direction, the concern is to minimize forward flow resistance and, in the reverse direction, the objective is to minimize flow reversal and avoid water hammer. Check valve manufacturers have often used counterweights to permit quick opening or quick closing. The drawback of forward flow counterweight check valves is that in the flow reverse direction, the counterweights may retard valve closure. The location of the counterweight could further complicate the performance of the check valve. Misaligning the counterweight can also affect check valve performance. The use of quick closing counterweights present similar challenges. This paper examines the interaction of counterweight location and alignment on the performance of check valves.
