Mutual coupling reduction of two PIFAs with a T-shape slot impedance transformer for MIMO mobile terminals

Abstract in UndeterminedAn efficient technique is introduced to reduce mutual coupling between two closely spaced PIFAs for MIMO mobile terminals. The proposed mutual coupling reduction method is based on a T-shape slot impedance transformer and can be applied to both single-band and dual-band PIFAs. For the proposed single-band dual PIFAs, the 10 dB impedance bandwidth covers the 2.4 GHz WLAN ban

Computations of the Flow around a Wind Turbine: Grid Sensitivity Study and the Influence of Inlet Conditions

The flow around a complete model wind turbine is computed using LES and the immersed boundary method. The influence of inlet velocity profile and turbulence level is evaluated. The inlet velocity profile was found to have major influence in the upper regions of the flow field. The imposed turbulence level had no major influence on the turbulent spectra but it's effect is clearly seen on the genera

Characterization of shear and compaction bands in a porous sandstone deformed under triaxial compression

The study of localized deformation in porous sandstones at the laboratory scale can yield valuable insights into the internal structures and mechanisms of shear zones and compaction bands that might impact on flow at a reservoir scale. Herein, we report results of a laboratory study of shear and compaction band formation in a porous sandstone using a range of full-field experimental techniques: ac

A microscopic investigation of miR-34c and miR-205 in Prostate Cancer

Popular Abstract in Swedish Förr trodde man att de delar av genomet som inte uttrycks till proteiner är oviktiga, eftersom man trodde att det nästan uteslutande är proteinerna som utför de nödvändiga funktionerna i cellen. Man kände till att DNA och RNA innehåller information om hur proteiner ska se ut och när de ska uttryckas, men man kände bara till ett fåtal andra uppgifter som RNA har i cellenThe complex genetics of cancer allows tumors to grow and spread undeterred by the control mechanisms of the cell. The importance of protein-coding genes in tumorigenesis is well established. Recently, microRNAs (miRNAs) have emerge as key regulator of development and cellular processes such as differentiation, cell growth and cell death; processes closely linked to cancer. The aim of this thesis w

A Closed Form Expression for the Exact Bit Error Probability for Viterbi Decoding of Convolutional Codes

In 1995, Best et al. published a formula for the exact bit error probability for Viterbi decoding of the rate R=1/2, memory m=1 (2-state) convolutional encoder with generator matrix G(D)=(1 1+D) when used to communicate over the binary symmetric channel. Their formula was later extended to the rate R=1/2, memory m=2 (4-state) convolutional encoder with generator matrix G(D)=(1+D^2 1+D+D^2) by Lent

Bioavailable phosphorus in humic headwater streams in boreal Sweden

Bioavailable phosphorus (BAP) concentrations were determined nine times between April and October 2010 in two humic boreal headwater streams draining forest-and mire-dominated catchments. BAP was analyzed in a bioassay in which natural P-limited bacterioplankton grew with natural P as the sole P source. In both streams, approximately 90% of the BAP occurred as dissolved species (passing a 0.2-mu m

GAD Antibody Positivity Predicts Type 2 Diabetes in an Adult Population

OBJECTIVE-To evaluate the significance of GAD antibodies (GADAs) and family history for type 1 diabetes (FHT1) or type 2 diabetes (FHT2) in nondiabetic subjects. RESEARCH DESIGN AND METHODS-GADAs were analyzed in 4,976 nondiabetic relatives of type 2 diabetic patients or control subjects from Finland. Altogether, 289 (5.9%) were GADA(+)-a total of 253 GADA(+) and 2,511 GADA(-) subjects participate

Characterization of insolubilized humic acid and its sorption behaviors

Insolubilized humic acid (IHA) was prepared in the laboratory by heating approach. Through the comparison between the endothermic peaks, optimal heating temperature was determined to be 330A degrees C. The modified IHA then was characterized by TG-DTA, SEM, FTIR, element analysis, and nitrogen adsorption-desorption isotherms. The removal efficiency of p-nitrophenol from the aqueous solution by ads

eavesROP: Listening for ROP Payloads in Data Streams (preliminary full version)

We consider the problem of detecting exploits based on return-oriented programming. In contrast to previous works we investigate to which extent we can detect ROP payloads by only analysing streaming data, i.e., we do not assume any modifications to the target machine, its kernel or its libraries. Neither do we attempt to execute any potentially malicious code in order to determine if it is an att

Bioreduction of carbonyl compounds to chiral alcohols by whole yeasts cells: process optimisation, strain design and non-conventional yeast screening

Chiral building blocks are needed for the production of drugs and fine chemicals, which requires the use of several synthetic routes to produce a specific enantiomer of interest. One promising approach to introduce chirality into molecules is the stereo-selective whole cell bioreduction of carbonyl compounds or ketones to the corresponding chiral alcohols. The aim of this thesis was to develop eff
