Substantiation of the influence of changes in the coefficient of axle distribution of braking force on the handling of a passenger car

The article considers the change of the radius of the instantaneous center of rotation of a car moving along a curved trajectory during braking, taking into account the lateral input of the wheels of both axles of cars, both equipped with electronic tracking systems and not equipped with such. A criterion for assessing the controllability of cars moving on a curved trajectory in a braked state, by comparing the ratio of the current speed of the car to the longitudinal base with the ratio of the coefficients of lateral tire input to the product of the longitudinal base of the car, mass and cosines. It is established that the radius of instantaneous rotation of the longitudinal axis of the car moving along a curved trajectory during braking depends on the speed of the center of mass of the car, the coefficient of axle distribution of braking force, physical characteristics of applied tires, steering wheel angle and design and weight parameters. As a result, it allows you to set controllability. The authors obtained dependences that will create new algorithms for the operation of modern electronic control systems for stabilizing the longitudinal axis of a braked car, taking into account the speed of the car, its design and weight characteristics, the main characteristics of its braking system (coefficient of axle braking force distribution), physical characteristics used tires on wheels and connect them to the angles of the steered wheels, controlling the deviation of the longitudinal axis, which allows the driver to maintain the possibility of quite sharp maneuvers directly in the braking process, moving along a curved trajectory.

The main means of ensuring a sentence execution in the form of restriction of liberty

Currently, the Republic of Uzbekistan is actively implementing reforms of the penal legislation and the Penal system. Their main tendency is to abandon the previously dominant opinion about the possibility of reducing crime by toughening penalties and to choose a course for strengthening and developing legal norms that promote greater individualization and differentiation of criminal responsibility. However, we have to admit that the current system of punishments does not have measures that can achieve the goal of correcting convicted persons without elements of isolation from society, but under the supervision of competent law enforcement agencies. The relatively rare use of the restriction of liberty, in the author's opinion, is explained by the insufficient development of the mechanism for its implementation, in particular, the means of ensuring its execution. The execution of a sentence in the form of restriction of liberty is ensured by a whole system of means that are closely interrelated. Conditionally, such means can be divided into two main groups: control-supervisory and psychological-educational means. Based on the results of the study, the author comes to the following conclusions. The enforcing means of liberty restriction are designed to create a reliable legal guarantee of the implementation of the principle of punishment inevitability and the fullest possible realization of the goals of punishment. Currently, there is no practice in Uzbekistan of using electronic means of control and supervision of persons sentenced to restriction of liberty. At the same time, only the implementation of the electronic tracking tools specified in the legislation for the control and supervision of persons sentenced to restriction of liberty, the definition of a specific order and methods of surveillance can affect the development of positive experience in the use of electronic bracelets in the Republic of Uzbekistan. A special category of persons sentenced to restriction of liberty is juveniles. When conducting educational work with them, it is necessary to take into account the factors that affect their behavior. In this regard, it is proposed to create a public organization consisting of juveniles at the age of 14 to 18 years, located at the inspection of the sentences execution of the internal affairs bodies and conducting educational activities with juveniles sentenced to restriction of liberty.

Linking Staff Cases in a Hospital COVID-19 Outbreak Using Electronic Tracking Data

Background: Significant outbreaks of SARS-CoV-2 infections have occurred in healthcare personnel (HCP). We used an electronic tracking system (ETS) as a tool to link staff cases of COVID-19 in place and time during a COVID-19 outbreak in a community hospital. Methods: We identified SARS-CoV-2 infection cases through surveillance, case investigation and contact tracing, and voluntary testing. For those wearing ETS badges (Centrak), data were reviewed for places occupied by the personnel during their incubation and infectious windows. Contacts beyond 15 minutes in the same location were considered close contacts. Results: Over 6 weeks (August 10–September 14, 2020), 35 HCPs tested positive for SARS-CoV-2 by NAAT testing. In total, 18 nurses and aides were clustered on 1 hospital unit, 7 cases occurred among respiratory therapists that visited that unit, and 10 occurred in other departments. Overall, 17 individuals wore ETS badges as part of hand hygiene monitoring. ETS data established potential transmission opportunities in 17 instances, all but 2 before symptom onset or positive test result. Contacts were most often (10 of 17) in common work areas (nursing stations), with a median time of 45 minutes (IQR, 21–137). Contacts occurred within and between departments. A few COVID-19 patients were cared for in this location at the time of the outbreak. However, we did not detect HCP-to-patient nor patient-to-HCP transmission. Conclusions: Significant HCP-to-HCP transmission occurred during this outbreak based on ETS location. These events often occurred in shared work areas such as the nursing station in addition to break areas noted in other reports. ETS systems, installed for other purposes, can serve to reinforce standard epidemiology.Funding: NoDisclosures: None

Marketing Strategies of Tuku Vocational High School’s (TKVS) Library in Taiwan

Traditionally, rather than using books in the library, a typical Asian student preferred reading and studying from textbooks in order to pass the college entrance examination. Likewise, this trend was the same in the small suburban town in Taiwan like Tuku with the area is 46 square kilometer, its population of 32,000 people, and 70% of its population is farmers. Due to its agriculture background, there are only two libraries to service its residents. One is the public high school’s library that belongs to Tuku Vocational High School that has approximately about 28 classes and 1000 students while the other is Tuku’s public library. Owing to the textbooks edition from one tomany, the exam content has changed a lot from the past to the present. In order to master the examination, multiple facets of literacy should be mastered. Because of this, library should be gaining popularity than before. In contrary, this was not the case. Library books were seldom checked out according to the electronic tracking system for library books. From three years ago, the average of books checked out was below 15 per day. That average has steady climbing to about 120 with the maximum around 370. Recently, by conducting an open-end questionnaires and chatting with its students, it was found that some marketing strategies are needed to educate them the importance of utilizing the books in the library as the primary source of mastering multi-facets of literacy instead of textbooks.

Design of Deployment Strategies to Monitor the Movement of Animals with Passive Electronic Devices

Current animal monitoring systems have improved our knowledge of quantitative animal ecology. There are many electronic tracking technologies such as VHF/UHF telemetry, light-level geolocation, ARGOS satellite telemetry and GPS tracking. To reach the desired level of information retrieval requires the planning of adequate equipment effort and coverage, which depends on the properties of the system. We propose an equipment arrangement model consisting of a given number of receiver stations in a two-dimensional space in which the animals move according to a central place movement model. The objective is to characterize how the transmission of tracking data depends on the movement of the animals and the design of the equipment deployment: quantity and location of the receiver stations and their associated reception radius. We also implement the model using real trajectories of southern elephant seals and Australian sea lions publicly available online and tracked during the years 2010–2012. We characterize the data transmission based on different equipment configurations and we obtained analogous results to the theoretical model.
