Study Of Dynamics Of The Twisting Process In Pneumomechanical Spinning In The Presence Of

Abduvakhidov Mubashirkhon,, Muradov Akramjon Abdusatorovich,, Sayidmuradov Mirzokhid Mirzarahimovich

Read Abstract

For the modern textile industry, one of the characteristic trends remains the desire to
increase the productivity of technological machines by increasing speed, which sets the task
of reducing the cost of electricity in pneumatic mechanical spinning, the successful solution
of which requires systematizing the accumulated information on new methods of shaping
yarn and structures of shaping and twisting devices to clarify a number of problems in the
development of the yarn forming method.

An Intuitive Framework For Displaying, Invigorating And Rendering Of Practically Characterized Articles

N. A. Kurasov, S. I. Marchenko, N. V. Mandrovskiy

Read Abstract

This paper depicts intelligent shape demonstrating of geometric articles characterized by
bother capacities. 3D objects dependent on the annoyance capacities have a preferred
position of spline portrayal of surfaces, that is, a serious extent of perfection, and a bit of
leeway of self-assertive structure for few bother capacities. Intelligent change of the capacity
based model with quick representation permits us to give both the intelligence and any
necessary degree of detail prompting a photograph sensible appearance of the subsequent
shapes. An intelligent framework displaying is introduced.

Application Of Signal Frequency Ortogonal Multiplexing In Dvb-T Standard

N.I. Juraeva, J.H. Hamraev

Read Abstract

The orthogonal frequency multiplexing, defined by the abbreviation OFDM, provides a
significant increase in the bandwidth of the radio channel due to the improvement in spectral
efficiency. In addition, the use of OFDM allows the transmission speed to be increased
without increasing the frequency range or modulation level. Therefore, OFDM is used in
modern wireless systems, such as IEEE 802.11 (Wi-Fi) and IEEE 802.16 (WiMAX), as well
as in wired ADSL.

An Epic Procedure For Raising The Unit Yield Of Huge Coordinated Machines

Abdullahi Begianpuye

Read Abstract

In power frameworks, the significant wellspring of electrical vitality is the simultaneous
generator. Be that as it may, the expansion in the unit size of the regular coordinated
generator has not stayed up with the comparing increment in the unit yield of central players
driving them, and the interest for electrical vitality continues developing. To this end, a novel
system for expanding the unit yield of coordinated generator is proposed in this paper. The
plan utilizes circuit hypothesis ideas and composite rotor attractive structure to enhance
Xd/Xq proportion on which the hesitance yield power depends without changing the physical
geometry of the machine. The investigation of the machine depends on airgap motion
thickness conveyances and transition linkages.

Research Of Technological Parameters Of Pattern Cotton-Silk Knitting Fabrics

Musayev Nuriddin Muxitdinovich , , Gulyayeva Gulfiya Harisovna,, Mukimov Mirabzal Mirayubovich

Read Abstract

In recent years, the country has been actively working on the development of the
textile, clothing and knitting industry, expanding the assortment and assortment of finished
products, as well as supporting investment and export activities of the sector. In the article
outlines the ways in which new knitted and knitted fabric can be used efficiently using local
raw materials. Production of new types of knit fabrics using natural silk will not only expand
the use of natural silk, but will also expand the range of knitted fabrics and improve their
quality, consumption and especially hygienic properties. Manufactured cotton-silk knitted
fabric was fabricated in a 18-gauage knitting machine made of Germany`s Mayer & Cie
OVJA 1.6 ET. In the article results of analyses of technological parameters patterned knitted
fabrics, worked out with purpose effective using of locals raw materials and produced

Quality Properties Of Vitellaria Paradoxa-Spread Nuts Under Compressive Stacking

Nakpodia, L. R.

Read Abstract

Pressure tests were performed on heat-rewarded Vitellaria paradoxa margarine nuts to
contemplate the impacts of temperature and stacking position on break power, distortion,
strength and immovability of the nuts. The elements analyzed effectsly affected the
deliberate boundaries (crack power, twisting, durability and immovability) at 95% certainty
level. Break power, disfigurement and sturdiness diminished while solidness expanded with
increments in temperature in both pivotal and parallel stacking positions. Higher estimations
of solidness however lower estimations of break power, disfigurement and sturdiness were
acquired when Vitellaria paradoxa-spread nuts were compacted in sidelong stacking position
contrasted and hub stacking position under similar conditions.

Mr. Pushpendra Kumar, Mr. Devendra Bisen,

Read Abstract

The present serious world requests speed. On the off chance that we are moderate, at that
point we will be a washout. Giving security quickly is the point of this paper. Social database
are significant for fulfilling the present enlightening needs. Progressively critical stage is
forestalling its possession rights. In prior existing framework security was given by sending
the scrambled social database to the customer framework without compacting its size
consequently doesn't speeds up move rate. To conquer this confinement we are utilizing
pressure method which will give security also speeds up information move between
customers to server framework.
