We consider a cooperative relaying system which consists of a number of source terminals, one shared relay, and a common destination with multi-packet reception (MPR) capability. In this paper, we study the stability and delay analysis for two cooperative relaying schemes; the sensing-based cooperative (SBC) scheme and the decision-based cooperative (DBC) scheme. In the SBC scheme, the relay se...

This paper presents a 24-bit 5.0 GHz ultrahigh-speed direct digital synthesizer (DDS) with direct digital modulation capabilities used in a pulse compression radar. This design represents the first DDS RFIC in over-GHz output frequency range with direct digital modulation capabilities. It adopts a ROM-less architecture and has the capabilities for direct digital frequency and phase modulation w...

The present study investigated the anti-oxidative effects of xylitol both in vitro and in vivo in normal and type 2 diabetes (T2D) rat model. Free radical scavenging and ferric reducing potentials of different concentrations of xylitol were investigated in vitro. For in vivo study, six weeks old male Sprague-Dawley rats were divided into four groups, namely: Normal Control (NC), Diabetic Contro...

This paper presents the investigation of convolutional neural network (CNN) prediction successfully recognizing temperature nonequilibrium phase transitions in two-dimensional (2D) Ising spins on a square lattice. The model uses image snapshots ferromagnetic 2D spin configurations as an input shape to provide average output predictions. By considering supervised machine learning techniques, we ...

This work presents a 24 ?GHz integrated Phase-Locked Loop in 60 sliding-IF transceiver for IEEE 802.15.3c standard with low phase noise. For noise, varactor and MOM cap combination method is applied this PLL. The capacitor bank optimized to decrease the noise folding from circuit within method. analog PLL fabricated 65 ?nm CMOS technology of ?98.8 dBc/[email protected] ?MHz, reference spur ?62....

This work concerns the production of fibrous composite materials based on biodegradable polymers such as alginate, dibutyryl chitin (DBC) and poly-ε-caprolactone (PCL). For the production of fibres from these polymers, various spinning methods were used in order to obtain composite materials of different composition and structure. In the case of alginate fibres containing the nanoadditive trica...

Introduction With the introduction of the DBC system in 2005, the funding of Dutch health care gradually began to change. The DBC system is replacing the current system of position-based budgeting (block grant) of providers and the lump-sum funding of medical specialists. In 2005, two segments were introduced for somatic health care. An A-segment, with fixed national tariffs for health provider...

Computational Grids and peer-to-peer (P2P) networks enable the sharing, selection, and aggregation of geographically distributed resources for solving large-scale problems in science, engineering, and commerce. The management and composition of resources and services for scheduling applications, however, becomes a complex undertaking. We have proposed a computational economy framework for regul...

Fractal Dimension (FD) is an essential feature of fractal geometry that characterizes the surface roughness of complex or irritated objects. Though, fractal dimension gradually established its importance in the area of image processing by means of image segmentation, Pattern recognition, texture and medical signal analysis and many more. A number of algorithms for estimation of fractal dimensio...

Introduction The Dutch DBC-system was developed and implemented between 2000 and 2005. When compared to other members of the 'classification family tree' it can be concluded that the system is not a logical step in the general line of development of classification systems. On a number of characteristics the Dutch system stands out from the other systems. One major differing characteristic being...
