Detailed description of Capacity and Level of service of Multi lane highways based on Highway Capacity Manual (HCM2010) along with one example for finding LOS of a highway
Rotaries are intersections where traffic moves in one direction around a central island. They convert severe conflicts into milder merging and diverging movements. Some advantages are lower speeds, fewer accidents, and self-regulation without signals. Rotaries are suitable for moderate traffic volumes up to 3000 vehicles/hour and work best when traffic from all approaches is balanced. Their capacity depends on entry/exit widths, weaving width and length, and proportion of weaving traffic.
The document defines different types of traffic volumes used for transportation planning and design. Daily volumes like average annual daily traffic (AADT) are used to establish trends over time. Hourly volumes like the peak hour volume are most important for design and operational analysis. Within the peak hour, the peak 15-minute volume and peak hour factor (PHF) account for fluctuations in flow. Sub-hourly volumes below 15 minutes are also sometimes analyzed.
The document discusses the geometric design of roads, specifically horizontal curves. It covers key elements of geometric design like alignment, profile, and cross-section. Horizontal curve design is an important part that influences safety and efficiency. Parameters like design speed, superelevation, extra widening, and minimum radius are discussed in detail according to Indian Road Congress standards.

Low power architecture of logic gates using adiabatic techniquesnooriasukmaningtyas
The growing significance of portable systems to limit power consumption in ultra-large-scale-integration chips of very high density, has recently led to rapid and inventive progresses in low-power design. The most effective technique is adiabatic logic circuit design in energy-efficient hardware. This paper presents two adiabatic approaches for the design of low power circuits, modified positive feedback adiabatic logic (modified PFAL) and the other is direct current diode based positive feedback adiabatic logic (DC-DB PFAL). Logic gates are the preliminary components in any digital circuit design. By improving the performance of basic gates, one can improvise the whole system performance. In this paper proposed circuit design of the low power architecture of OR/NOR, AND/NAND, and XOR/XNOR gates are presented using the said approaches and their results are analyzed for powerdissipation, delay, power-delay-product and rise time and compared with the other adiabatic techniques along with the conventional complementary metal oxide semiconductor (CMOS) designs reported in the literature. It has been found that the designs with DC-DB PFAL technique outperform with the percentage improvement of 65% for NOR gate and 7% for NAND gate and 34% for XNOR gate over the modified PFAL techniques at 10 MHz respectively.
Advanced control scheme of doubly fed induction generator for wind turbine us...IJECEIAES
This paper describes a speed control device for generating electrical energy on an electricity network based on the doubly fed induction generator (DFIG) used for wind power conversion systems. At first, a double-fed induction generator model was constructed. A control law is formulated to govern the flow of energy between the stator of a DFIG and the energy network using three types of controllers: proportional integral (PI), sliding mode controller (SMC) and second order sliding mode controller (SOSMC). Their different results in terms of power reference tracking, reaction to unexpected speed fluctuations, sensitivity to perturbations, and resilience against machine parameter alterations are compared. MATLAB/Simulink was used to conduct the simulations for the preceding study. Multiple simulations have shown very satisfying results, and the investigations demonstrate the efficacy and power-enhancing capabilities of the suggested control system.

CHINA’S GEO-ECONOMIC OUTREACH IN CENTRAL ASIAN COUNTRIES AND FUTURE PROSPECTjpsjournal1
The rivalry between prominent international actors for dominance over Central Asia's hydrocarbon
reserves and the ancient silk trade route, along with China's diplomatic endeavours in the area, has been
referred to as the "New Great Game." This research centres on the power struggle, considering
geopolitical, geostrategic, and geoeconomic variables. Topics including trade, political hegemony, oil
politics, and conventional and nontraditional security are all explored and explained by the researcher.
Using Mackinder's Heartland, Spykman Rimland, and Hegemonic Stability theories, examines China's role
in Central Asia. This study adheres to the empirical epistemological method and has taken care of
objectivity. This study analyze primary and secondary research documents critically to elaborate role of
china’s geo economic outreach in central Asian countries and its future prospect. China is thriving in trade,
pipeline politics, and winning states, according to this study, thanks to important instruments like the
Shanghai Cooperation Organisation and the Belt and Road Economic Initiative. According to this study,
China is seeing significant success in commerce, pipeline politics, and gaining influence on other
governments. This success may be attributed to the effective utilisation of key tools such as the Shanghai
Cooperation Organisation and the Belt and Road Economic Initiative.

42. The Russell Square-
Panthapath road is
basically a commercial
based residential area. So
therefore this area have
a large amount
of high-rise buildings. In
this road 3 hospitals are
situated. A lots of the fast-
food shop, furniture shop,
bus counter are there

60. OBSERVATION
The main and basic problem is observed there
is geometric design. Lane width, Footpath,
Divider, Cross section are not designed
properly.
Presence of lot of side roads is another
problem for this road as they always
interrupted the main flow of the road.
Heterogeneous vehicle flow is another main
problem for this section. Non-motorized
vehicle causes traffic congestion as they are
main obstruction for high speedy vehicle.
Traffic police in this section is inadequate in
numbers com-pared to other place in Dhaka
61. OBSERVATION
Streets of this section are not that wide spread,
due to illegal possession on the road they are
getting narrow and becoming a reason behind
traffic jam.
Illegal parking on the road has been creating
congestion every day from Russell square to
Panthapath, a distance of around two
kilometers. On-road parking of vehicles is one
of the main reasons behind serious traffic
congestion on different parts of the road.
Lack of automatic traffic signals, proper sign
and marking is another basic problem in this
section.
62. RECOMMENDATION
A ‘windshield survey’ would also have
generated better results, & led to a more
detailed conclusion.
Removal of potholes for the free flowing
vehicular movement is important for
increasing travel speed & decreasing travel
time.
Road surface, markings and signs should be
well designed and maintained
Law enforcement agency be more active in
enforcing traffic.
Raise awareness among pedestrians about
road safety and encourage them to use
footpaths in a regular and orderly manner
signalling devices positioned at road intersections, pedestrian crossings and other locations to control competing flows of traffic
Primary signal: in approach , before crossing intersection , at right hand
Secondary signal: in approach , after crossing intersection , at right hand
Tertiary signal: the hanging signal used for high speed road, where the driver can see the signal from a very far point . and there is no reason for using this in this street
