Identification of Modal Parameters of a Rocket
ISBN: 9783838351254 / Angielski / Miękka / 2010 / 80 str. Termin realizacji zamówienia: ok. 10-14 dni roboczych (Bez gwarancji dostawy przed świętami) Modal parameters of spacecraft structures are important indicators of their dynamic characteristics which can be used for vibration reduction and control. In the present research modal parameters of a rocket are identified by using continuous wavelet transformation. The advantages of the wavelet transformation for the modal parameters identification over other methods is study. Through finite element method transient dynamic response of a system is determined then continuous wavelet transformation is applied to find the modal parameters like modal frequency, mode shapes and damping ratio.

Optimization of Sheet Metal Forming Process
ISBN: 9783838344843 / Angielski / Miękka / 2010 / 92 str. Termin realizacji zamówienia: ok. 10-14 dni roboczych (Bez gwarancji dostawy przed świętami) Numerical simulations of sheet metal forming process based on finite element method (FEM) is widely applied for its powerful capability in forming process prediction. Since there are parameters which could affect the result of forming process, it becomes important to approach a set of parameters to improve the formability. In the present work, first, a comprehensive literature review was made for different optimization methodologies in sheet metal forming process. Then we proposed an optimization methodology using Response Surface methodology (RSM) and Genetic Algorithm (GA) for the...

Design and Analysis of Grid Stiffened Composite Structures
ISBN: 9783838351841 / Angielski / Miękka / 2010 / 72 str. Termin realizacji zamówienia: ok. 10-14 dni roboczych (Bez gwarancji dostawy przed świętami) Composite stiffened panels have been used in aerospace industries for past decades. Due to light weight nature composite panels are prone to buckling. In this study buckling load for Ortho-grid panel and Iso-grid panel is determined. This was accomplished by developing a composite laminate for both skin and stiffener using MSC PATRAN/NASTRAN was used for linear buckling analysis of composite panels. The buckling loads of two panels were determined based on finite element analysis results, including geometric dimension, thickness of the skin, number of laminae, ply stacking sequence, thickness...

Parthenium its Survey and Competition with Weeds and Vegetables
ISBN: 9783846523414 / Angielski / Miękka / 136 str. Termin realizacji zamówienia: ok. 10-14 dni roboczych (Bez gwarancji dostawy przed świętami) Parthenium hysterophorus has become a major weed of various areas of the country in a relatively short time. In the present study the detailed survey of district Sialkot with total 53 sites was conducted to evaluate the extent of infestation of Parthenium hysterophorus. Along with P. hysterophorus a great number of other weeds were also observed during the survey. Among the waste lands of Sialkot infestation of P. hysterophorus was more than 50%, along the road side was 60%, the waterways 46% and along the crop fields was 56% and at the banks of rice fields and Trifolium sp. and in fallow...

Quantum Dots for Plant Systems
ISBN: 9783031102158 / Angielski / Twarda / 2022 / 192 str. Termin realizacji zamówienia: ok. 22 dni roboczych (Bez gwarancji dostawy przed świętami) Quantum dots (QDs) are important in the research and industrial fields due to their diverse properties and technological importance. Recently, QDs have been found to be suitable for biological, biomedical, agricultural, and food science applications. Many research articles, review papers, and internet sources have published on the use of QDs to improve plant growth and yield, but a comprehensive overview in book form has not been available to date. This book provides detailed information on synthesis, functionalization, and the use of various types of quantum dots for plant systems. It also...

Bioconversion Efficacy Of Pleurotus By Using Different Agro-Wastes
ISBN: 9783846502013 / Angielski / Miękka / 92 str. Termin realizacji zamówienia: ok. 10-14 dni roboczych (Bez gwarancji dostawy przed świętami) A large amount of agro-waste is produced annually world over. Agricultural straw consists mainly of cellulose, hemicellulose and lignin, the most abundant renewable biopolymer. Much of this material is disposed of by burning, which results in environmental pollution; only a little is used as a feed for ruminants. The use of fungi for conversion of lignocellulosic waste into food and feed rich in protein have gained importance as an alternative for developing unconventional source of proteins. Species of Pleurotus (oyster mushroom) represents the second largest variety of the mushroom in the...

Epicuticular Wax Barrier in Cotton
ISBN: 9783848437948 / Angielski / Miękka / 104 str. Termin realizacji zamówienia: ok. 10-14 dni roboczych (Bez gwarancji dostawy przed świętami) In this study the role of epicuticular wax in transmission of CLCuV has been studied. Epicuticular waxes plays very important role in hindering the attachment of insects to the leaves. In this study the wax deficient mutant plants GaWM3 were used as experimental plants while Gossypium arboreum (786) were used as negatively controlled plants as it is reported that whitefly can not transmit virus in it and G. hirsutum (MNH-93) were taken as negative and positive control plants because it has severe viral attack in past. It is important to mention here that GaWM3 were produced in our laboratory...
