We study linear metric perturbations around a spherically symmetric static spacetime for general $f(R,\mathcal{G})$ theories, where $R$ is the Ricci scalar and $\mathcal{G}$ Gauss-Bonnet term. find that, unless determinant of Hessian zero, even-type have ghost any multipole mode. In order these theories to be plausible alternatives relativity, theory should satisfy condition that massive enough effectively decouple from other fields. requirement on form which satisfies this condition. also...
The study focuses on the characteristics of urban heat island (UHI) in Bangkok, Thailand. Hourly air temperature data from four weather stations -one rural site and three sites for last five year are used to intensities UHI Bangkok area. results indicate presence it is increasing terms intensity. reveals maximum intensity around 6-7 °C detected during dry season. mean annual city higher by 0.8 than outside city. conditions (wind, cloud, precipitation), different land cover types major...
We calculate how strongly one can constrain the alternative theories of gravity with deci-Hz gravitational wave interferometers such as DECIGO and BBO. Here we discuss Brans-Dicke theory massive graviton typical examples. consider inspiral compact binaries composed a neutron star (NS) an intermediate mass black hole (IMBH) for (BD) those super (SMBH) theories. Using restricted 2PN waveforms including spin effects taking precession into account, perform Monte Carlo simulations 104 to estimate...
In recent years, the number of traffic accidents caused by elderly drivers has increased in Japan. However, a car is an important mode transportation for elderly. Therefore, to ensure safe driving, system that can assist required. this study, we propose driver-agent provides support during and after driving encourages them improve their driving. This paper describes prototype based on analysis teaching records human instructor, subjective evaluation driver from three different agent forms,...
In this study, we propose a user-interruptibility estimation method based on focused application switching (AS) during PC work. It was experimentally demonstrated that the interruptions of AS are more acceptable than those continuous Therefore, constructed an algorithm estimates interruptibility at three levels 19 selected indexes. The feasibility by experiment using another dataset 11 users.
Introduction to Black Hole Physics is a large volume (504 pages), and yet despite this it still really an introductory text. The book gives introduction general relativity, but most of the text dedicated attracting reader's attention interesting world black hole physics. In sense, very distinct from other textbooks on relativity. We are told that was based lectures given by Professor Frolov, one authors, over last 30 years. One can obtain basic ideas about holes, also necessary tips...
Thiel's embalming method provides natural coloration, flexibility, and tissue plasticity, is used widely to prepare specimens for cadaver surgical training. However, this causes brain softening, thereby restricting the training of intra-cranial procedures. In study, three cadavers were embalmed using formalin fixation, method, with additional intra-cerebral ventricular injection, respectively. We also established rat models methods develop determine best retaining adequate elasticity. The...
Thailand's urban planning was stuck in a growth paradigm that concentrated on land-use management to respond the population and economic since 1975. However, most provincial cities have experienced decline. As result, many of cities' comprehensive plans are unable foster sustainable development their respective cities. Meanwhile, little attention has been paid this topic. Consequently, study attempts emphasize existence shrinking Thai system alongside neglect government manage phenomenon by...
Urban heat islands (UHIs) are a global phenomenon. They particularly evident in expansive urban centers such as Bangkok, Thailand's capital. Recent research has highlighted the escalation of temperatures and poor ventilation due to severe urbanization. Nevertheless, scant attention been paid both temperature wind distribution. Concurrently, imperatives development policies require integration environmental climatic factors. In this context, present study delves into UHIs Bangkok dynamics...
Frequent and uncontrolled interruptions by information systems that do not reflect the user's state can result in fragmented working times decreased intellectual productivity. To avoid adverse interruptions, interruptibility estimation methods based on PC operation have been proposed. However, workers who use PCs to accomplish their primary tasks occasionally engage paperwork. Occasional paperwork activities, which are reflected PC's information, cause errors. This study focuses using...
