Integrated CPU Monitoring Using 2D Temperature Sensor Arrays Directly Printed on Heat Sinks

AbstractIn today's digital world, the demand for computer security and system reliability is a crucial element. Monitoring the CPU temperature during operation provides valuable insights but is currently limited to the embedded on‐chip sensors. The implementation of an extra security layer based on temperature monitoring can detect anomalies in an early stage, identify malware, and help mitigate attacks. The approach of integrating more on‐chip temperature sensors into the silicon is avoided due to space, power limitations, and cost constraints. However, the field of printed electronics and sensor technology has recently seen significant progress. This is the first work that introduces a fully‐printed temperature sensor array integrated onto the cooling unit of a CPU. It offers a novel approach for the practical implementation of such sensors into an operational computer system. The present sensor array, consisting of 396 sensor pixels, detects local hotspots induced by the underneath CPU cores, leading to an individual thermal fingerprint. This unique method paves the way for addressing pivotal elements of computer security, as deviations from expected thermal behavior can signal malicious activities. Additionally, this innovation facilitates reliability optimization. The detailed thermal map garnered provides insights into which cores are subjected to significant stress over time.

CLASSIFICATION AND METHODS OF DETECTION OF PHISHING ATTACKS

The reliable operation of data transmission networks, computer systems and mobile devices is a mandatory condition for the effective functioning of the state and society, and the life of an individual. The reliability of key information systems for public use depends on many factors: cyber attacks, hardware and software failures, and various types of errors. Rapid expansion of threats to national security in the 21st century. entrusts state authorities with the tasks of their prevention, detection and neutralization. Cyber security is increasingly viewed as a fundamental problem of the state, which comprehensively affects its security, defense, economy, and almost all spheres of public life. The Internet gave a powerful impetus to the development of mass communication, trade and information exchange. However, today it is the area where many crimes are committed. The impersonal nature of digital infrastructure has made identity theft a natural and highly attractive project. Cybercriminals actively use various means of stealing information, including phishing. At the current stage and in the future, the development of both individual societies and states, as well as the world in general, will be carried out in accordance with the concept of the information society, which is connected with the use of information and telecommunication technologies in the acquisition, storage and processing of information in everyday life Phishing is a serious online security problem that involves spoofing genuine websites to trick online users and steal their confidential information. Analyzing these definitions, we can conclude that “phishing” can be considered in different ways, but the main purpose of its conduct remains unchanged—stealing data. The practical value of the results lies in the possibility of using the obtained classifier for further creation of software solutions for recognizing phishing sites. It, as well as a set of characteristics, can be implemented in anti-phishing browser extensions or other anti-phishing tools.

Spatiotemporal modulations in acoustics: From nonreciprocity to mechanical computing

Spatially graded materials have been a cornerstone of acoustic metamaterials for decades, enabling wave manipulation across different length scales. Likewise, structures with time-varying material properties have gained traction in wave filtering applications. Put together, systems exhibiting concurrent spatial and temporal modulations of one or more parameters (e.g., stiffness or phase) can unlock an array of new features ranging from nonreciprocal propagation to frequency-dependent wave beaming. In this talk, we will introduce the notion of dynamic phase gradients, i.e., a spatial phase shift between neighboring elements (of a metasurface) or transducers (of a phased array) which also varies in time. Through theory and experiments, we will demonstrate that the resultant systems are capable of (a) generating multiple scattered harmonics of a single input which simultaneously propagate in different directional lanes, each carrying a unique frequency footprint, and (b) exhibiting non-identical beaming patterns in transmission and reception by breaking time invariance. We will present an application of this concept in the development of a mechanical neural network via reconfigurable elastic metasurfaces, designed to perform a computational task. Since the frequency channels of a spatiotemporally-modulated metasurface are independently tunable, they can be assigned distinct tasks, thus allowing parallel operations in mechanical computing systems.

Fermat's Two Page Claim of his Last Problem Verified

In the 1650s Fermat claimed a short two-page proof of his last theorem but could not fit it into the margin. This article vindicates Fermat’s claim that has never been verified. The proof of Fermat’s claim has held up for over 360 years. The solution to the problem given in this article shows that the problem can be solved in two pages and clarifies why the problem resisted solution by thousands of mathematicians both professional and amateur. The author solved the problem in 1998 but opted not to publish it until recent years. However, the author featured the proof publicly in his website challenging anyone to find a flaw in the proof. No objections ever occurred. The proof uses only theorems and proof techniques available to Fermat. It is a devious proof that can be understood by a gifted high school student because it only uses theorems taught in high school along with an interesting algorithm devised by the author for the purpose of addressing infinity issues obstructing the finding of a simple two-page solution. The algorithm invented by the author ended the quest to solve the theorem and allows the viewer of the proof to understand why this problem has resisted so many attempts. The author believes this solution is the only one possible. The author Dr. Joseph E. L. Brierly is skeptical about the many-page solution claimed by Sir Andrew Wiles some years ago. Even professional mathematicians avoid attempting to verify pages of subtle reasoning. There is a strong likelihood of errors in proofs of that magnitude. As everyone knows a computer operating system invariably has multiple bugs due to the large number of lines of coding. In essence, there is no reason for an impractical-to-verify solution taking pages of subtle reasoning when there exists an easily reviewed two-page solution given in this research article. There exist few important theorems in mathematics and physics that require more than 5 pages of reasoning.

These advanced technologies make medical businesses more and more dependent on industry information and data, which brings about network system security issues that cannot be ignored. To strengthen the daily operation and management of hospitals, ensure the stable operation of computer systems, and do a good job in protecting the security of hospital computer system network information, this paper designs a risk assessment method for hospital computer network information security based on SAE deep neural network and analyzes the main factors affecting the security of hospital computer system network information. The experimental results prove that the proposed method can effectively improve the reliability of the evaluation results and ensure the accuracy of the evaluation results. According to the obtained information security model, it can effectively guide the construction and application of hospital computer network information systems, optimize the system network, and promote the development of hospital informatization.

THE STRUCTURE OF THE COMPUTER SYSTEM IN THE RESIDUAL CLASSES

The subject of the article is the formulation and solution of the inverse problem of optimal redundancy in the system of residual classes (RNS) based on the use of the dynamic programming method. The solution of this problem makes it possible to improve the reliability of the operation of computer systems and components (CSC) in the RNS. The purpose of the article is to increase the reliability of the functioning of CSC, which are built on the basis of the use of RNS, without reducing the speed of calculations, as well as to calculate and compare the reliability, in terms of the probability of failure-free operation, of CSC in RNS and a tripled computing system that operates in a positional binary number system (PNS). Tasks: to analyze the influence of the number system used on the reliability of the CSC, taking into account the primary and secondary redundancy; to synthesize a computing system in RNS for a l-byte bit grid based on the use of the passive fault tolerance method (constant structural redundancy); formulate and solve the inverse problem of optimal redundancy in RNS based on the use of the dynamic programming method; to check the correctness of the results obtained, calculate the conditional amount of computer system equipment in the residual classes; evaluate the efficiency of using RNS to improve reliability when building a redundant CSC in relation to a redundant CSC in the PNS. Research methods: methods of analysis and synthesis of computer systems, number theory, coding theory in RNS, reliability theory. The following results are obtained. The paper shows that the use of PNS as a number system does not allow a radical increase in the performance and reliability of CSC. In this regard, the article developed the concept of using RNS as a number system for constructing a CSC. Based on this, the inverse problem of optimal redundancy in RNS is formulated and solved. Conclusions. As shown by the results of calculations and comparative analysis, the use of RNS provides a higher reliability of the CSC than the majority three-channel computing system in the PNS. The obtained research results can be used for the synthesis of fault-tolerant computer structures in RNS.

This article presents an alternative approach to strategic planning for the development of territorial communities. The essence of this method is an integral approach by the territorial community to the use of available resources necessary for its development with differential planning of specific operational tasks for a specific time. An urbanized system is considered as a spatial, hierarchically structured functional system. Strategic planning is based on the principles of organization and development of systems through their resources, processes and structure. The methodology of strategic planning is based on a hierarchical representation of the object, determining the efficiency of urbanized systems. The methodology includes three stages: description, strategy modeling, and implementation. Based on the systemic and structural analysis of the object, a standard scheme for describing the city and its functional subsystems has been developed, which includes structure, resources, and processes. Each of them is characterized by indicators of different hierarchical levels - absolute, group, complex and integral. Each of the characteristics has a name, type, type, value, and unit of measurement. The analysis of the object and the evaluation of its functioning efficiency are carried out taking into account the efficiency, environmental friendliness and comfort of the urban environment. To determine the effectiveness of strategic planning of the city, the author proposes methods for assessing the efficiency, environmental friendliness and comfort. They are suitable for use at different hierarchical levels and will allow to evaluate the effectiveness of the strategy, development programs, plans, and projects. This methodology allows you to create an operational computer system for modeling, researching, and managing the development of systems depending on changes in the external characteristics of the structure, processes, and resources.

Greenhouse gas abatement via repurposing computers

The purpose of this research is to generate findings to support the reduction of computer supply chain greenhouse gas emissions. This is achieved by answering the question, ‘can greenhouse gas abatement be delivered by alternative computer operating system displacement strategies?’ We hypothesised that extending the useful lifespan of end user computing devices to 8 years by repurposing a device with a new operating system can reduce scope 3 supply chain emissions, which account for 73% of an end user computing device's carbon footprint. To test the hypothesis, we measure the carbon footprint reduction delivered by repurposing 3,150 obsolete desktop computers, which were installed with a Linux based operating system to become thin clients and support a remote working solution for a major financial institution during the recent Covid-19 pandemic. We calculate scope 3 supply chain emissions avoided by not purchasing new thin client solutions. Legacy device power consumption is also measured and extrapolated to represent the one-year period of use and compared with that of new devices to calculate the excess scope 2 emissions of the former. We find that while new devices reduce scope 2 emissions, this gain is outweighed by the reductions in scope 3 emissions from not replacing the legacy devices. Furthermore, we find that the new Linux based operating system reduces energy consumption by 22% compared with Microsoft Windows. We also calculate the financial gains from the repurposing strategy to test the perception that sustainable information technology adoption is costly. Finally, the impact of remote working on commuting emissions is estimated. In conclusion, the findings show that repurposing end user computing devices contributes meaningfully to sustainability strategies from both an environmental and financial perspective.
