The usage of slots has gained renewed interest in aerospace, particularly on propeller design. Most the works have focused improving aerodynamic performance and efficiency. Modern research design aims to propellers with high thrust under low torque conditions without any weight penalty. Although slotted been done before, none understand its impact different airfoils blade. Thus, this study prov...

The paper presents a new practical design for 4 × 1 planar switched array of dielectric filled waveguide antennas loaded with bow-tie shaped slots operating at 26.5 to 29.5 GHz 5G millimetre-wave applications. is realized as three-layered architecture, the top layer behaving radiator, bottom feed network and control circuit; common ground plane in middle layer, offering small form factor. are u...

An analysis of laminar natural convection in inclined slots subjected to patterned heating has been performed. The imposed takes a simple form characterized by single Fourier mode combined with uniform heating. It is shown that periodic applied at the lower plate produces no net flow when slot either horizontal or vertical, but upward generated tilted. Periodic upper downward situation. additio...

-In this paper, we examine a ready-to-use, robust, and computationally fast fixed-size memory pool manager with no-loops and no-memory overhead that is highly suited towards time-critical systems such as games. The algorithm achieves this by exploiting the unused memory slots for bookkeeping in combination with a trouble-free indexing scheme. We explain how it works in amalgamation with straigh...

We explore the problem of sharing network resources when users’ preferences lead to temporally concentrated loads, resulting in an inefficient use of the network. In such cases external incentives can be supplied to smooth out demand, obviating the need for expensive technological mechanisms. Taking a game-theoretic approach, we consider a setting in which bandwidth or access to service is avai...

We consider all-optical TDM/WDM broadcast and select networks with slotted operation. Each network access node is equipped with one fixed transmitter and one tunable receiver; tuning times are not negligible with respect to the fixed size slot time. We discuss efficient scheduling algorithms to assign TDM/WDM slots to multicast traffic in such networks. The problem is shown to be NP-hard; thus,...

This opinion article argues that noise (randomness) in neural activity is the limiting factor in visual working memory (WM), determining how accurately we can maintain stable internal representations of external stimuli. Sharing of a fixed amount of neural activity between items in memory explains why WM can be successfully described as a continuous resource. This contrasts with the popular con...

Previous works have proposed analytical models of TDM wavelength networks to evaluate the blocking performance, but they differ in their underlying assumptions and have varying computation complexities. In this paper, we propose an analytical model of TDM WDM optical networks with optical time-slot interchangers and without wavelength converter for minimum fixed hop routing. In order to make th...

It is commonly believed that visual short-term memory (VSTM) consists of a fixed number of "slots" in which items can be stored. An alternative theory in which memory resource is a continuous quantity distributed over all items seems to be refuted by the appearance of guessing in human responses. Here, we introduce a model in which resource is not only continuous but also variable across items ...

RTS-CTS handshake based protocols achieve “reliable unicast” by eliminating the hidden node problem effectively, however, these solutions are not directly or efficiently generalizable for solving the single-hop “reliable broadcast” problem, and broadcast remains as a best-effort operation in wireless ad hoc networks. Here we present a simple, light-weight, and self-stabilizing MAC protocol, nam...
