Abstract It is still little or no knowledge about the properties of layered wood-based composites and nonwood components in viscoelastic plastic region force-deflection diagram (FDD). The this area are influenced by several factors such as composition composite, method modification individual layers, type adhesive used, etc. This paper focuses on analysis effect thickness layers (5 9 mm) beech ...

In this paper we characterize the capacity of a UTRA-like Frquency Division Duplex (FDD) Code Division Multiple Access (CDMA) system employing Loosely Synchronized (LS) spreading codes. Current CDMA systems are interference limited, suffering from Inter-Symbol-Interference (ISI), since the orthogonality of the spreading sequences is destroyed by the channel. They also suffer from MultipleAccess...

Fault detection and diagnosis (FDD) is a critical approach to ensure safe and efficient operation of manufacturing and chemical processing plants. Multivariate statistical process monitoring (MSPM) has received considerable attention for FDD since it does not require a mechanistic process model. The diagnosis of the source or cause of the detected process fault in MSPM largely relies on contrib...

In a BFWA (Broadband Fixed Wireless Access Network) the evolved SINR (Signal to Interference plus Noise Ratio) is relevant influenced by the applied duplex method. The TDD (Time Division Duplex), especially adaptive TDD method has some advantage contrary to FDD (Frequency Division Duplex), for example the spectrum efficiency and flexibility. However these methods are suffering several new inter...

The current paper proposes intelligent Fault Detection and Diagnosis (FDD) approaches, aimed to ensure the high-performance operation of Wind energy conversion (WEC) systems. First, an efficient feature selection algorithm based on particle swarm optimization (PSO) is proposed. main idea behind use PSO remove irrelevant features extract only most significant ones from raw data in order improve ...

In order to achieve a higher gain in frequency division duplex (FDD) massive multiple-input multiple-output (MIMO) system, it is imperative feedback downlink channel state information (CSI) from user equipment (UE) base station (BS). However, excessive overhead makes the task challenging. Hence, recent years, various deep learning (DL)-based models have been introduced effectively compress CSI ...
