Interference and compatibility issues relating to coexistence of twoduplexing modes in UMTS, FDD and TDD, are highlighted in this paper.Performance degradation due to co-existence is quantified by comparingwith single system scenarios. It has been found that systemperformance depends on the loading of both FDD and TDD. Co-existence can be optimised when some compromise is ob...

Since 1976, the Software Engineering Laboratory (SEL) has been dedicated to understanding and improving the way in which one NASA organization, the Flight Dynamics Division (FDD) at Goddard Space Flight Center, develops, maintains, and manages complex flight dynamics systems. It has done this by developing and refining a continual process improvement approach that allows an organization such as...

The aim of the study was to determine impact commercially available hydrotreated vegetable oil (HVO) and its mixture (HVO5, where 5% (v/v) HVO 95% FDD) with diesel fuel (FDD) on power, torque, consumption, exhaust gas composition an atmospheric internal combustion engine used in off-road applications. Diesel as comparative fuel. Testing realized a full-load mode KOHLER KDI 1903 M 3-cylinder SIE...

Functional dependency with degree of satisfaction (FDd) is an extended notion in data modeling, and reflects a type of integrity constraints and business rules on attributes, mainly for massive databases, in which incomplete data such as noise, null and imprecision may exist. While existing approaches are considered effective in general, attempts for further improvement in efficiency are deemed...

BACKGROUND/AIMS The causes of functional anorectal outlet obstruction (outlet obstruction) include functional defecation disorder (FDD), rectocele, and rectal intussusception (RI). It is unclear whether outlet obstruction is associated with rectal hyposensitivity (RH) in patients with functional constipation (FC). The aim of this study was to determine the association between RH and outlet obst...

This paper presents some measurements supporting the spectral compatibililty of a T1.413 FDD PSD mask compliant non-stationary service with a DMT service that is using bit swapping. EtherLoop technology modems use a Spectrum Manager function to monitor the line between bursts, and upon detecting significant coupling with an ADSL type service, switch to a safe mode of operation [1]. This safe mo...

The performance of a multi-rate mobile cellular network using the Frequency Division Duplex (FDD) mode of the Code Division Multiple Access (CDMA) based Universal Mobile Telecommunication System (UMTS) is investigated. The new call blocking and call dropping probabilities and the tolerable network load are studied in the context of a multi-rate FDD-mode UMTS network incorporating dynamic thresh...

Abstract Negative foreign direct investment (divestment) between countries has received little attention in international macroeconomics. This is the first country-level study to investigate whether conventional drivers of bilateral (FDI) have a reverse, but symmetric, impact on divestment (FDD). Using negative and positive FDI data 126 or territories, from 2005 2018, we find that gravity varia...

Detecting and diagnosing HVAC faults is critical for maintaining building operation performance, reducing energy waste, ensuring indoor comfort. An increasing deployment of commercial fault detection diagnostics (FDD) software tools in buildings the past decade has significantly increased buildings’ operational reliability reduced consumption. A massive amount data been generated by FDD tools. ...
