JAVA For the code in which I implemented most of the quick select algorithm. Quick select is a O(n) time algorithm to find the nth smallest value in an (unordered list). The following recursive algorithm finds thenth smallest element with an index bewtween left and right in list: Code: Solution A multi-year effort to prevent hackers from altering computers while they boot up has largely failed because of lax application of preventive steps, researchers say, despite disclosures that flaws are being actively exploited. In the latest sign that the problem persists, researchers at the federally funded MITRE lab said this week that many customers of Intel still had not adopted revised security designs Intel distributed in March after the MITRE team found new vulnerabilities in the start-up process. That could mean many newer Windows computers remain exposed, the MITRE team said ahead of a presentation at the Black Hat security conference in Las Vegas next week. Intel’s point person on the issue, Bruce Monroe, said he did not know how many suppliers and computer makers had followed Intel’s recommendations. “We’re not privy to whether they’ve fixed it or not,” Monroe said. “We asked them to let us know.” The glitches illustrates how well-funded spying programs as those exposed by former National Security Agency contractor Edward Snowden can continue to succeed against targets that depend on a complex supply chain. Long before Snowden’s documents began appearing in the media, professional technicians and US officials were concerned about the vulnerabilities that left computers severely exposed as they are turned on. Years ago, then-US National Security Agency Director Keith Alexander privately urged the chief executives of major American technology companies to do something about the boot-up procedure known as the Basic Input/Output System, or BIOS..

Final Research Project - Securing IoT Devices: What are the Challenges? Internet security, in general, is a challenge that we have been dealing with for decades. It is a regular topic of discussion and concern, but a relatively new segment of internet security is getting most attention—internet of things (IoT). So why is internet of things security so important? The high growth rate of IoT should get the attention of cybersecurity professionals. The rate at which new technology goes to market is inversely proportional to the amount of security that gets designed into the product. According to IHS Markit, “The number of connected IoT devices worldwide will jump 12 percent on average annually, from nearly 27 billion in 2017 to 125 billion in 2030.” IoT devices are quite a bit different from other internet-connected devices such as laptops and servers. They are designed with a single purpose in mind, usually running minimal software with minimal resources to serve that purpose. Adding the capability to run and update security software is often not taken into consideration. Due to the lack of security integrated into IoT devices, they present significant risks that must be addressed. IoT security is the practice of understanding and mitigating these risks. Let’s consider the challenges of IoT security and how we can address them. Some security practitioners suggest that key IoT security steps include: 1. Make people aware that there is a threat to security; 2. Design a technical solution to reduce security vulnerabilities; 3. Align the legal and regulatory frameworks; and 4. Develop a workforce with the skills to handle IoT security. Final Assignment - Project Plan (Deliverables): 1) Address each of the FOURIoT security steps listed above in terms of IoT devices. 2) Explain in detail, in a step-by-step guide, how to make people more aware of the problems associated with the use of IoT devices.

Malware detection in IoT environments necessitates robust methodologies. This study introduces a CNN-LSTM hybrid model for IoT malware identification and evaluates its performance against established methods. Leveraging K-fold cross-validation, the proposed approach achieved 95.5% accuracy, surpassing existing methods. The CNN algorithm enabled superior learning model construction, and the LSTM classifier exhibited heightened accuracy in classification. Comparative analysis against prevalent techniques demonstrated the efficacy of the proposed model, highlighting its potential for enhancing IoT security. The study advocates for future exploration of SVMs as alternatives, emphasizes the need for distributed detection strategies, and underscores the importance of predictive analyses for a more powerful IOT security. This research serves as a platform for developing more resilient security measures in IoT ecosystems.

Network security is one of the foremost anxieties of the modern time. Over the previous years, numerous studies have been accompanied on the intrusion detection system. However, network security is one of the foremost apprehensions of the modern era this is due to the speedy development and substantial usage of altered technologies over the past period. The vulnerabilities of these technologies security have become a main dispute intrusion detection system is used to classify unapproved access and unusual attacks over the secured networks. For the implementation of intrusion detection system different approaches are used machine learning technique is one of them. In order to comprehend the present station of application of machine learning techniques for solving the intrusion discovery anomalies in internet of thing (IoT) based big data this review paper conducted. Total 55 papers are summarized from 2010 and 2021 which were centering on the manner of the single, hybrid and collaborative classifier design.

It’s our second all-Equifax “Open Source Insight,” as the Equifax breach unfortunately still leads the cybersecurity and open source security news cycle this week. As the Equifax breach has shown, open source security risks are a daunting reality. But that breach should never have happened — a known, fixable open source vulnerability not being remediated. Open source software — such as Apache Struts — comprises 80 to 90 percent of the code in modern applications, yet most organizations lack any visibility into the open source they are using. In response, Black Duck, the global leader in automated solutions for securing and managing open source software, announced this week the availability of a free-use tool that enables organizations to determine if they are at risk from the Apache Struts vulnerability that was exploited in the recent, high-profile Equifax breach.

Cyber forensics is use of scientific methods for definite description of cybercrime activities. It deals with collecting, processing and interpreting digital evidence for cybercrime analysis. Cyber forensic analysis plays very important role in criminal investigations. Although lot of research has been done in cyber forensics, it is still expected to face new challenges in near future. Analysis of digital media specifically photographic images, audio and video recordings are very crucial in forensics This paper specifically focus on digital forensics. There are several methods for digital forensic analysis. Currently deep learning (DL), mainly convolutional neural network (CNN) has proved very promising in classification of digital images and sound analysis techniques. This paper presents a compendious study of recent research and methods in forensic areas based on CNN, with a view to guide the researchers working in this area. We first, defined and explained preliminary models of DL. In the next section, out of several DL models we have focused on CNN and its usage in areas of digital forensic. Finally, conclusion and future work are discussed. The review shows that CNN has proved good in most of the forensic domains and still promise to be better.

Money and Our Monetary System The monetary system in any economy facilitates trade and allows people to trade more efficiently, as compared to a barter economy. In the United States, the monetary authority is the Federal Reserve System (also referred to as the Federal Reserve, or informally, as the “Fed”.) For this use the Fed’s website (http://www.federalreserve.gov/) when addressing the questions below. What are the requirements for something to be considered money? Why does the dollar have value? What does the money supply consist of and what are the respective amounts in the total money supply for the United States? What are the primary functions of the Fed? What role does the Federal Open Market Committee (FOMC) play in our economy? What role do the financial institutions (commercial banks and other institutions) play in our financial system? What is meant by the term “fractional-reserve banking” in our system? What are the implications for consumers? What are the tools available to the FED for controlling the money supply? Which are used most often? Which are most effective? How does the money multiplier help to determine the effects of monetary policy? What are the pros and cons of using monetary policy, as opposed to the use of fiscal policy, for implementing economic policies and practices? Solution Money is basically medium of exchange so for anything to be consideredd money there are three eligibility criterias It is a currency which is backed by a stable and sound government, other than that dollar has value because it fulfills all the three criteria mentioned above. It is widely accepted which provides good strength to its value. It consist of M1 and M2(the definitions and details are copied from fedreserve site) Money Stock Measures. Billions of dollars. There are four primar functions of Fed The role of FOMC is to make monetary policy for federal reserve stsrem which it could implement in the U.S. The most basic role of financial institutions is to provide circulate money in the economy and facilitate liquidity. It enables the flow of economic activities and helps in spreading the effects of implemented monetary policies.Table 1 Money Stock Measures.

hi i need to produce a 300 word report on the construction of structures aligned to the railway infrastructure and explaine the impact of track engineering construction. and my report should include examples from the following tunnels, side bridges, sea defences, platforms, operatinal bulidings, platform awnings, mast and towers. iv started to answer the report but im not to sure if iv stuck to rigth path of the question. so i wounder if any one called help me. Solution Railway is like a lifeline to a country. Most.of the people and goods are transported through railways. As railway runs mostly on land , in order to make it accessible to most part of the land supporting structures are made. Some of them are discussed below. Tunnels- These structures are mainly made when the terrain are rough or they are at very high altitude. At very high altitude it becomes difficult to travel and if travelling is done it is done at very low speed. It is basically carried out in hilly areas. So to overcome this problem tunnels are being constructed in the hills. This solve 2 main purposes. Firstly it reduces the travel time and secondly it connects the places. Side bridges- They are mainly constructed in order to connect the places divided by a water , valley etc. Sea Defences- They are mostly constructed along the sea shore. When a railway passes through sea , it is very likely that it will get affected by its tides. In order to neutralize it sea defences are made to avoid water coming on the tracks and also to avoid soil erosion beneath the tracks. Platform Awnings- Thes structures are mainly above the platforms. These are basically shed type of structures. They can solve many purposes. Firstly they provide shed and shelter to people beneath. Then they lower the temperature from around 5-8 . Installation of solar panels above them can lead to generation of electricity. Platforms- They serve the purpose of people boarding in and out of train. They also act as waiting area for passengers. They are designed according to train length and height. A busy station has more no of platform compared to less busy one as more no of persons are arriving and departing at a busy station compared to less busy one. Mast- They are constructed to hold the electric cables. These cables provide electricity for the train to run. Towers- They are constructed basically for signaling system..

How does multicore differ from a classic multiprocessing environment? Solution Multicore is differ from Multi processing because A multiprocessor systems having more than one central processing unit and allowing them to work in parallel. This is known as Simultaneous Multiprocessing. A multicore central processing unit has many execution cores on one CPU it means different things depending on the correct design but basically it means that a definite subset of the CPU\'s components is duplicate so multiple cores can work in parallel on separate operations. This is known as Chip level Multiprocessing..

How the non-dense index works? How the non-dense index works? Solution Dense Index: An index record appears for every search key value in file. This record contains search key value and a pointer to the actual record. This makes searching faster but requires more space to store index records itself. Index records contain search key value and a pointer to the actual record on the disk. A non-dense index has: One entry for each block One entry for each different value Sparse Index is non-dense index In sparse index, index records are not created for every search key. An index record here contains a search key and an actual pointer to the data on the disk. To search a record, we first proceed by index record and reach at the actual location of the data. If the data we are looking for is not where we directly reach by following the index, then the system starts sequential search until the desired data is found..

Answer the following questions from the Article below: Exercise #1. Read the following article and then answer the following questions in paragraph form. 1. How has DNA changed the study of biology over the past 50 years? Explain whether scientists have shifted to a molecular level in the various subdisciplines of biology. Also, do you believe any trend to the molecular level will continue far into the future? 2. Explain the role of DNA in the development of an organisms. Does DNA fully provide a blueprint to create an individual? Can DNA by itself propagate itself or does it require other molecular machines? 3. In modern biology, which is the role of physics in the study of organisms and their molecules? Has physics moved to the forefront or does it play an ancillary role? As described in the article, why are the molecular forces of very low energy in an organism? Historians have the luxury of looking back at human endeavor over long periods of time, but most scientists are too busy working in the present and thinking anxiously about the future and have no time to view their work in the context of what has gone before. I once remarked that all graduate students in biology divide history into two epochs: the past 2 years and every- thing else before that, where Archimedes, Newton, Darwin, Mendel—even Watson and Crick—inhabit a time-compressed universe as uneasy contemporaries. It seems remark- able that historians once thought that science progressed by the steady addition of knowledge, building the edifice of scientific truth, brick by brick. In his 1962 book The Struc- ture of Scientific Revolutions, Thomas Kuhn argued that progress occurs in revolutionary steps by the introduction of new paradigms, which may be new theories—new ways of looking at the world—or new technical methods that enhance observation and analysis. Between Kuhn’s revolutions, scientif ic knowledge does advance by accretion, as there is much to do to consolidate the new science. But then, inevitably, unsolved problems accumulate and, in many cases, the inconsis- tencies have been put to one side and every- body hopes that they will quietly go away. The edifice becomes rickety; some of its founda- tions are insecure and many of the bricks have not been well-baked. This is when a new revolutionary wave in the form of new ideas or new techniques appears, which allows us to condemn and demolish the unsafe or corrupt parts of the edifice and rebuild truth. Often there is great resistance to the new wave, but as Max Planck pointed out, it succeeds because the opponents grow old and die. The process is then repeated: The radicals become liberals, the liberals become conservatives, the conservatives become reactionaries, and the reactionaries disappear. Students of evolu- tion will recognize this process in the theory of punctuated equilibrium: Organisms stay much the same for very long periods of time; this is interrupted by bursts of change when novelty appears, f.

All answers are in the form of True/False with a explantion as to why: 1) An ideal band-pass filter centered (at ± 0) can be created by just multiplying the sinc function by cos(0t) in the the time domain. 2) Nyquist theorem deals with windowing of a signal in the time domain, which is translated into leakage in the frequency domain. 3) The global frequency response of an LTI system composed of two LTI systems in parallel with each other is simply the addition of the individual frequency responses of the systems. 4) We can find the H(j) of an unknown LTI system by stimulating it with a impulse and taking the Fourier Transform of its response. Another more realistic way is to stimulate the LTI system with a unit step function (signal), take the Fourier Transform of its response, multiply it by (j) for every 0 and divide it by pi at =0. ^I believe that one is true, but I am needing help forming an explanation. 5) A first step towards sampling an unknown analog signal without aliasing is to low-pass filter the signal. Solution 1) False Because fourier transform of sinc function is rectanctangular function in frequency domain, and fourier transform of cos function is impuse function. So when when multiply in time domain that means convoution in frequency domain. And if ve convolude rectangular function with impulse function then it would be rectangular pulse train. Which is not ideal band paas filter at w=0. 2) False It would be either window or leakage in time domain or frequency domain. 3) TRUE It is simply understand by block reduction method in control system. When there is another forward block we add both maid forward block with secondry forward block. OR LTI is linear in nature so add in parallel and multiply in series. 4) TRUE Its because the response or tansfer function of any system is called impulse response. It means when the input is Impuse function what is the output of that system. Same as the relation between unit imulse response and impuse respone in just fouries tranfer of unit step function. Because the fourier transform of impulse is unity. so if input is unit step function multiply it by (j) for every 0 and divide it by pi at =0.(1/(i)+(),) 5)FALSE Low paas filter use after sampling to recover the original signal..

Consider miRNA target sites, How do these compare to transcription factor binding sites? Imagine that both miRNA target sites and transcription factor binding sites were dispersed randomly in the genome ? Which would be likely to appear more frequent? Solution mRNA localization: mRAN location is critical for regulation of gene expression by allowing spatially regulated protein production. Through mRAN localization protein are transcribed in their intended target site of the cell. This is especially important during early developement when rapid cell cleavages give different cells various combinations of mRNA which can then lead to drastically different cell fates.RBPs are critical in the location of this mRNA that insures protein are only transcribed in ttheir intended regions. One of these proteins is ZBp1 binds to beta- actin mRNA at the site of transcription and moves with mRNA into the cytoplasm. It then localizes this mRNA to the lamella region of several asymmetric cell types where it can then be translated. FMRP is another RBP involved in RNA localization. It was shown thatt in addition to other functions for FMRP in RNA metabolism, FMRP is involved in the stimulus-induced localization of several dendritic mRNAs in neuronal dendrites. Transcription factors binding site: Transcrption factors bind to either enhancer or promoter regions of DNA adjacent gene is either up- regulated. Transcription factors use a varity of mechanisms for the regulation of gene expression. These mechanisms include: Histone acetyltransferase (HAT) activity - acetylates histone proteins, which weakens the association of DNA with histones, which make the DNA more accessible to transcription, thereby up- regulating transcription. Hiestone deacetylase (HDAC) activity - deacetylates histone proteins, which strengthens the asociation of DNA with histones, which make the DNA less accessible to transcription, thereby down- regulating transcription. Activation: trancsription factors may be activated (or deactivated) through their signal- sensing domain by a number of mechanism including:.

Anaerobic Respiration & Fermentation (Microbiology) What are the bubbles in fermented medium made of? Describe the process that they come from. Solution Answer: The bubbles in the fermented medium is made of carbon dioxide and hydrogen. Microbes ferment glucose/dextrose to produce gases such as carbon dioxide and hydrogen. The medium most commonly used is phenol red glucose broth and is composed of 0.5-1.0% glucose. As the broth gets fermented, acidic end products are produced. This reduces the pH of the media which can be detected as the phenol red changes its colour from red to yellow. Inverted tubes called Durham tubes can be attched to the tubes of the broth which trap any carbon dioxide produced as a result of fermentation..

4. Pick out any text-mining tool that impressed you the most and discuss an overview of its text mining process, sentimental & speech analytics. Solution LanguageWare is a natural language processing (NLP) technology developed by ibm, which allows applications to process natural language text. It comprises a set of Java libraries which provide a range of nlp functions: language identification, text segmentation/tokenization, normalization, entity and relationship extraction, and semantic analysis and disambiguation. The analysis engine uses Finite state machine approach at multiple levels, which aids its performance characteristics, while maintaining a reasonably small footprint. Speech analytics: Speech analytics allows users to analyse and extract information from both live and recorded conversations. It is being used effectively to gather intelligence for security purposes, to enhance the presentation and utility of rich media applications, and perhaps most significantly, to deliver quantitative business intelligence through the analysis of the millions of recorded calls . Sentiment analysis: Sentiment analysis is a branch of speech analytics that focuses specifically on assessing the emotional states displayed in a conversation. One common use of sentiment analysis within contact centres is to provide insight into a customer’s feelings about an organisation, its products, services, customer service processes, as well as its individual agent behaviours..
