As a member of the United Nations Committee on the Peaceful Uses of Outer Space (COPUOS), Iran has a long-term space exploration program. Space radiation is one of the challenges facing humans when they go outside Earth's protective atmosphere and magnetic field. Space is an environment that the cardinal principles of radiation protection i.e. time, distance and shielding cannot be effectively ...

Modelling varying speaking style remains a challenge to state of the art speech recognition and synthesis systems. Vowel and consonant reduction have been identified as correlative to speaking style variation, but still lack a common measurement. The reduction phenomena are often observed without consideration of coarticulation and assimilation effects, and as a result of speaking rate variabil...

Previous research demonstrated that voters for the Dutch radical right party PVV were most stable among highly volatile electorate. However, since 2017 two new parties have successfully entered Parliament: Forum Democracy (FvD) and JA21, conceivably at expense of PVV. The success these is puzzling, because there does not seem to be much room campaigning on a similar platform. In our paper, we u...

The present study examines the acoustic vowel space of Greek and Turkish vowels produced by bilingual speakers. The results are presented for both languages’ vowels production by bilingual speakers, as well as compared with the vowels production by monolingual speakers. It is revealed that the acoustic space of the Greek vowels produced by bilingual speakers is larger than the acoustic space of...

mohammed, north, and ashton find that decentralization in fiji shifted health-sector workloads from tertiary hospitals to peripheral health centres, but with little transfer of administrative authority from the centre. decisionmaking in five functional areas analysed remains highly centralized. they surmise that the benefits of decentralization in terms of services and outcomes will be limited....

We use goal babbling, a recent approach to bootstrapping inverse models, for vowel acquisition with an articulatory speech synthesizer. In contrast to motor babbling, goal babbling organizes exploration in a low-dimensional goal space. While such a goal space is naturally given in many motor learning tasks, the difficulty in modeling speech production lies within the complexity of acoustic feat...

Searching and tracking people in crowded urban areas where they can be occluded by static or dynamic obstacles is an important behavior for social robots which assist humans in urban outdoor environments. In this work, we propose a method that can handle in real-time searching and tracking people using a Highest Belief Particle Filter Searcher and Tracker. It makes use of a modified Particle Fi...

The boundary element method is an efficient algorithm for simulating acoustic propagation through homogeneous objects embedded in free space. conditioning of the system matrix strongly depends on physical parameters such as density, wavespeed and frequency. In particular, high contrast density across a material interface leads to ill-conditioned discretisation matrix. Therefore, convergence Kry...

HULL, E. M., E. CHAPIN AND C. KASTANIOTIS. Effects of crowding and intermittent isolation on gerbils (Meriones unguiculatus). PHYSIOL. BEHAV. 13(6) 723-727, 1974. Gerbils were reared from weaning to adulthood in mixedsex paired, crowded or isolate-crowded conditions, the latter consisting of placing crowded animals into individual boxes for 2 hr per day. Paired males exhibited more ventral mark...
