UAV-Assisted and Intelligent Reflecting Surfaces-Supported Terahertz Communications

Abstract: In this letter, unmanned aerial vehicles (UAVs) and intelligent reflective surface (IRS) are utilized to support terahertz (THz) communications. To this end, the joint optimization of UAV’s trajectory, the phase shift of IRS, the allocation of THz sub-bands, and the power control are investigated to maximize the minimum average achievable rate of all users. An iteration algorithm based on successive Convex Approximation with the Rate constraint penalty (CAR) is developed to obtain UAV’s trajectory, and the IRS phase shift is formulated as a closed-form expression with introduced pricing factors. Simulation results show that the proposed scheme significantly enhances the rate performance of the whole system.

Football supporters’ perceptions of their role in the home advantage

Abstract: Football fans' views on their role in the home advantage were obtained by placing links to an internet questionnaire on supporters' websites. Altogether, 461 fans from clubs which had been promoted, relegated or unchanged in the past season of the English football leagues rated crowd support as significantly more influential than familiarity, travel, territoriality and referee bias in contributing to the home advantage. Fans felt responsible for inspiring their team to victory, took credit for distracting opponents, and believed that they could influence officials into making decisions in their team's favour. However, they did not accept personal blame for poor results. No effects for gender, age or the team's outcome in the promotion/relegation battle emerged, though season ticket holders were more extreme in their feelings of responsibility overall. Furthermore, it was suggested that mechanisms such as the perception of being superior to rivals can encourage fans to retain their allegiance to their teams, even when outcomes are disappointing. Indeed, affiliation may become so incorporated into self-identity that supporters may not have the option of abandoning their team, but instead perceive a reciprocal relationship in which both they and the team are expected to do their best to achieve success.

Theoretical analysis of control properties for the brushless doubly fed reluctance machine

Abstract: The brushless doubly fed induction machine (BDFIM) has been extensively researched for approximately 30 years, but a related machine [the brushless doubly fed reluctance machine (BDFRM)], has not. This was mainly due to the fact that reluctance rotor designs were not capable of generating saliency ratios large enough to make the BDFRM competitive with other machines. However, recent developments in reluctance rotors, spurred on by research into synchronous reluctance machines, has resulted in high saliency ratio rotors that are economic to build. This, together with the promise of higher efficiency and simpler control compared to the BDFIM, means that further investigation of the BDFRM is warranted. A relatively limited amount of work to date has been published on the BDFRM. This paper attempts to fill this void by presenting a theoretical analysis of some of the important control properties of the ideal BDFRM.

A comparison of offenders with intellectual disability across three levels of security

Abstract: Background A number of authors have described, with disparate results, the prevalence of people with intellectual disability and their characteristics, in a range of offender cohorts defined by service use. These have included high security, a range of criminal justice services and community services. There is a need for research comparing cohorts of offenders with intellectual disabilities across different settings. Aim and hypothesis To conduct such a comparison and test the hypothesis that severity of characteristics measured will be highest in highest levels of residential security. Method A clinical-record-based comparison a offenders with intellectual disability in high security (n = 73), medium/low security (n = 70), and a community service (n = 69). Results Groups were similar in age and tested IQ levels. Early psychiatric service contact had been more likely in the lower security groups. In line with the hypothesis, more complex presentations, in particular comorbid personality disorder, was more likely in the highest security group. Both fatal and non-fatal interpersonal violence convictions were significantly related to group, with more in the high security group sustaining a conviction both at the index offence and prior to that. Over 50% of all groups had at least one conviction for a sexual offence. A regression model accounting for 78% of the variance was made up largely of disposal variables (Mental Health Act status and probation) and indications of antisocial traits (criminal damage, lifetime conviction for murder and ICD-10 personality disorder classification). Conclusions and implications for practice The authors show that context of sampling affects most relationships between intellectual disability (ID) and offending when the methods for measuring ID are held constant. The results also present several questions on the relationship between risk, services available in an area and referral to higher security.
