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.
Harnessing WebAssembly for Real-time Stateless Streaming PipelinesChristina Lin
Traditionally, dealing with real-time data pipelines has involved significant overhead, even for straightforward tasks like data transformation or masking. However, in this talk, we’ll venture into the dynamic realm of WebAssembly (WASM) and discover how it can revolutionize the creation of stateless streaming pipelines within a Kafka (Redpanda) broker. These pipelines are adept at managing low-latency, high-data-volume scenarios.
Online aptitude test management system project report.pdfKamal Acharya
The purpose of on-line aptitude test system is to take online test in an efficient manner and no time wasting for checking the paper. The main objective of on-line aptitude test system is to efficiently evaluate the candidate thoroughly through a fully automated system that not only saves lot of time but also gives fast results. For students they give papers according to their convenience and time and there is no need of using extra thing like paper, pen etc. This can be used in educational institutions as well as in corporate world. Can be used anywhere any time as it is a web based application (user Location doesn’t matter). No restriction that examiner has to be present when the candidate takes the test.
Every time when lecturers/professors need to conduct examinations they have to sit down think about the questions and then create a whole new set of questions for each and every exam. In some cases the professor may want to give an open book online exam that is the student can take the exam any time anywhere, but the student might have to answer the questions in a limited time period. The professor may want to change the sequence of questions for every student. The problem that a student has is whenever a date for the exam is declared the student has to take it and there is no way he can take it at some other time. This project will create an interface for the examiner to create and store questions in a repository. It will also create an interface for the student to take examinations at his convenience and the questions and/or exams may be timed. Thereby creating an application which can be used by examiners and examinee’s simultaneously.
Examination System is very useful for Teachers/Professors. As in the teaching profession, you are responsible for writing question papers. In the conventional method, you write the question paper on paper, keep question papers separate from answers and all this information you have to keep in a locker to avoid unauthorized access. Using the Examination System you can create a question paper and everything will be written to a single exam file in encrypted format. You can set the General and Administrator password to avoid unauthorized access to your question paper. Every time you start the examination, the program shuffles all the questions and selects them randomly from the database, which reduces the chances of memorizing the questions.
HEAP SORT ILLUSTRATED WITH HEAPIFY, BUILD HEAP FOR DYNAMIC ARRAYS.
Heap sort is a comparison-based sorting technique based on Binary Heap data structure. It is similar to the selection sort where we first find the minimum element and place the minimum element at the beginning. Repeat the same process for the remaining elements.
A review on techniques and modelling methodologies used for checking electrom...nooriasukmaningtyas
The proper function of the integrated circuit (IC) in an inhibiting electromagnetic environment has always been a serious concern throughout the decades of revolution in the world of electronics, from disjunct devices to today’s integrated circuit technology, where billions of transistors are combined on a single chip. The automotive industry and smart vehicles in particular, are confronting design issues such as being prone to electromagnetic interference (EMI). Electronic control devices calculate incorrect outputs because of EMI and sensors give misleading values which can prove fatal in case of automotives. In this paper, the authors have non exhaustively tried to review research work concerned with the investigation of EMI in ICs and prediction of this EMI using various modelling methodologies and measurement setups.

2. Oil Well cementing is the process of mixing
a slurry of cement and water and displacing
it down the casing, tubing or drill pipe to a
pre specified point in the well
Two types of cementing process
Primary cementing
Secondary cementing
CEMENTATION
3.
4. PRIMARY CEMENTATION
The cementing takes place soon after the
lowering of casing is called primary cementation.
It is the process of mixing a slurry of cement
and water and pumping it down through steel
casing of the critical points in the annulus
between casing and open hole.
5. MAIN FUNCTIONS
• To bond and support the casing
• Protect the casing from corrosion.
• To restrict fluid movement between formations
• Protecting the casing from shock loads
• Sealing-off problematic zones.

8. Three most commonly used techniques :-
1. Single stage cementation
2. Multi stage cementation
3. Liner cementation
TECHNIQUES
9. SINGLE STAGE CEMENTING
It is the Most common technique
Normally accomplished by pumping
one batch of cement down the
casing between two rubber plugs.
The bottom plug is placed in the
casing, followed by cement slurry.
When the batch of cement has
been pumped into the casing, a top
plug is released.
The top plug is pumped down until
it lands on the top of float collar,
thus completing the cement job.
18. CEMENT AND ADDITIVES
Cement
• Class ‘G’ Oil Well Cement
Chemicals & Additives
Used to change the properties of cement slurries.
• Accelerators
• Retarders
• Fluid Loss Additives
• Friction Reducer
• Defoamer

20. ANY CEMENTING OPERATION THAT OCCUR
AFTER THE PRIMARY CEMENTING OPERATION.
TYPES OF SECONDARY CEMENTATION
PLUG CEMENTING
SQUEEZE CEMENTING
SECONDARY CEMENTATION
21.
22. PLUG CEMENTING
In plug cementing, a cement plug of a
specified length is placed across a
selected interval in an open or a cased
hole.
The cement is normally pumped through
open-ended drill pipe or tubing.
24. Reasons for setting a cement plug
1. To stop lost circulation during drilling.
2. Directional drilling and side tracking.
3. To plug back a depleted zone.
4. Abandonment.
5. To provide anchor for open hole test tool.

30. SQUEEZE CEMENTING
The most common remedial method
used today is squeeze cementing.
In squeeze cementing -
The slurry is forced by pressure to a
specified point in the annulus to cause
a seal at the point of squeeze.
31. CLASSIFICATION BY PRESSURE
1. LOW PRESSURE SQUEEZING.
2. HIGH PRESSURE SQUEEZING.
SQUEEZING TECHNIQUES
1. BRADENHEAD.
2. PACKER SQUEEZE.
34. CLASIFICATION BY PRESSURE
LOW PRESSURE SQUEEZING
Injection pressure < formation
fracture pressure
Cavities and interconnected voids
filled with dehydrated cement
Volume of cement small
Perforation and channel clear of
mud and other solids
Small node of cement filter cake
with properly designed slurries
Highest success rate
35. CLASIFICATION BY PRESSURE
HIGH PRESSURE SQUEEZE
Injection pressure > formation
fracture pressure
Channels not directly connected to
perforations
Impossible to remove plugging
material inside perforations
Placement accomplished by
breaking down formation
Location & orientation of fracture
not controlled.
37. Applications :
1. Supplement a faulty primary cement job.
2. Reduce water/oil, water/gas, or gas/oil ratio.
3. Repair casing leaks.
4. Stop lost circulation in open hole while drilling.
5. Supplement primary cement around a liner by
squeezing the top of the liner (during primary
cementation)
6. Sealing leakage of the liner top (in case of failure
after primary cementation).
7. Abandonment of single zones.
