A hybrid approach to machine-tool selection through AHP and simulation
(Taylor & Francis, 2007)
The selection process of a machine tool has been a critical issue for companies for years because the improper selection of a machine tool might cause many problems having a negative effect on productivity precision ...
A combined fuzzy AHP-goal programming approach to assembly-line selection
(IOS Press, 2007)
In mass production assembly-line balancing (ALB) problem has been a critical and repetitive issue for companies for long time. On the other hand equipment selection for stations has also been another important problem at ...
Joint data detection and channel estimation for uplink MC-CDMA systems over frequency selective channels
(Springer, 2007)
This paper is concerned with joint channel estimation and data detection for uplink multicarrier code-division multiple-access (MC-CDMA) systems ill the presence of frequency fading channel. The detection and estimation ...
Prevention of complications in laparoscopic hysterectomy: Experience with 1120 cases performed by a single surgeon
(Elsevier Science, 2007)
STUDY OBJECTIVE: The aim of this study is to describe a safe technique without any ureteral DESIGN: Prospective study (Canadian Task Force classification II-3). SETTING: Centre Hospitalier Interregional Edith Cavell ...
Iterative channel estimation and decoding of turbo coded SFBC-OFDM systems
(IEEE, 2007)
We consider the design of turbo receiver structures for space-frequency block coded orthogonal frequency division multiplexing (SFBC-OFDM) systems in the presence of unknown frequency and time selective fading channels. ...
Thermal rearrangement of 2-acetoxy-266-trimethylbicyclo[3.1.0]hexane: Theoretical elucidation of the mechanism
(Elsevier Science, 2007)
Bicyclohexenes are believed to be the immediate precursors of aromatic compounds. As a part of the exploratory study of thermal aromatization reactions 266-trimethylbicyclo[3.1.0]hexan-2-ol and its ester derivative ...
Design of practical matching networks with lumped elements via modeling
(IEEE, 2007)
It is a common practice to utilize commercially available software tools to design matching networks for wireless communication systems. Most of these tools require a properly selected matching network topology with good ...
Performance of space-time coded systems with transmit antenna selection
(IEEE, 2007)
We deal with transmit antenna selection for space-time coded (STC) systems over multiple input multiple output (MIMO) channels. Using pairwise error probability analysis and simulation results we show that transmit antenna ...
Reflectance-based Foster impedance data modeling
(Fachverlag Schiele Schon, 2007)
A reflectance-based method is presented to model a set of given Foster impedance data as a lossless singly terminated two-port consisting of lumped-elements in short or open termination. The basis of the new method rests ...
Posterior vitrectomy under topical anesthesia
(Elsevier, 2007)
Background: To determine the safety and efficacy of topical anesthesia in posterior vitrectomy. Methods: A total of 93 patients (93 eyes) with various vitreoretinal diseases not needing scleral buckling and with short ...
