Finding hidden objects in space is a fundamental ability that has received considerable research attention from both a developmental and a comparative perspective. Tracking the rotational displacements of containers and hidden objects is a particularly challenging task. This study investigated the ability of 3-, 5-, 7-, and 9-year-old children and great apes (chimpanzees, bonobos, gorillas, and...

This paper presents a new multilevel one-cycle control (OCC) technique for five-level diode-clamped converter (DCMC)-based static VAR compensator (STATCOM). The OCC algorithm in combination with multi-carrier level-shifted PWM is used the proposed DCMC-based STATCOM. automatic dc link voltage balance simply realized by four compensators presented as part of controller. In this principle two-lev...

A 20 year old boy presented to the dermatology department for treatment of a congenital icthyosis with a history of generalized erythroderma and trauma related blistering since birth. At the time of presentation he was noted to have red hyperkeratotic plaq corrugated over the joint flexures, elbows, knees after birth erythema and blistering improved but patient developed hyperkeratotic scaling ...

The main concern about the bi-directional AC-DC converter is to maintain utility power factor near to unity. One Cycle Controller (OCC) is one of the outstanding control techniques to control these power electronic converters. One Cycle Controller comprises one integrator with reset along with a few linear components like analog comparators, flip-flops, and a clock. This paper presents a hardwa...

Pseudoxanthoma elasticum (PXE) is a rare hereditary disorder of elastin fibers, characterized by yellowish coalescent papules in flexural surfaces with abnormally lax and corrugated skin. It can be associated to systemic manifestations mostly regarding eyes and vessels. Aesthetic surgery of cutaneous hyperlaxity was described in the international literature only in few cases, mostly as neck lif...

We conducted 2 experiments to examine how mothers structure directions to young children for finding hidden objects and how young children use these directions to guide their searches. In Experiment 1, we examined the reference frames mothers use to communicate with their 2.5-, 3-, and 3.5-year-old children about location by asking mothers to verbally disambiguate a target hiding container from...

In the first part of this paper we study minimal representations of simply connected simple split groups G of type Dk or Ek over local nonarchimedian fields. Our main result is an explicit formula for the spherical vectors in these representations. In the case of groups over R and C, such a formula was obtained recently in [8]. We also use our techniques to study the structure of the space of s...

The Open Cellular Convection (OCC) associated with cold air outbreaks is a common phenomenon over the North Sea where large number of wind parks are presented. Thus, reliable numerical simulations OCC events have great importance for offshore energy. We investigate ability to simulate using Weather Research and Forecast (WRF) model ERA5 reanalysis data as initial lateral boundary conditions OSI...
