Hands in the Honeypot

A honeypot is a program, machine, or system put on a network as bait for attackers. The idea is to deceive the attacker by making the honeypot seem like a legitimate system. A honeynet is a network of honeypots set up to imitate a real network. Honeynets can be configured in both production and research environments. A research honeynet studies the tactics and methods of attackers. A production honeynet is set up to mimic the production network of the organization. This type of honeynet is useful to expose the organizations current vulnerabilities. Honeypots return highly valuable data that is much easier to interpret than that of an IDS (Intrusion Detection System). The information gathered from honeypots can be used to better prepare system administrators for attacks. This paper focuses on the description and analysis of honeypots as well as how and where they are used. I describe the process of setting up and running a honeypot. Commands and associated output is provided to demonstrate how one would configure and install a honeypot. I set up two honeypots in an air-gapped security lab to test their effectiveness. I used the Nmap vulnerability scanner to test each of the honeypots in terms of their ability to emulate various operating systems and services. I also describe any potential problems that I encountered during my testing. This paper also takes a look into the mind of the enemy. Recommendations for honeynets are provided. © S A N S In st itu te 2 00 2, A ut ho r r et ai ns fu ll ri gh ts .

Detection of Abnormalities in Real-Time Computer Network Traffic Empowered by Machine Learning

This research discloses how to utilize machine learning methods for anomaly detection in real-time on a computer network. While utilizing machine learning for this task is definitely not a novel idea, little literature is about the matter of doing it in real-time. Most machine learning research in PC network anomaly detection depends on the KDD '99 data set and means to demonstrate the proficiency of the algorithms introduced. The emphasis on this data set has caused a lack of scientific papers disclosing how to assemble network data, remove features, and train algorithms for use inreal-time networks. It has been contended that utilizing the KDD '99 dataset for anomaly detection is not appropriate for real-time network systems. This research proposes how the data gathering procedure will be possible utilizing a dummy network and generating synthetic network traffic by analyzing the importance of One-class SVM. As the efficiency of k-means clustering and LTSM neural networks is lower than one-class SVM, that is why this research uses the results of existing research of LSTM and k-means clustering for the comparison with reported outcomes of a similar algorithm on the KDD '99 dataset. Precisely, without engaging KDD ’99 data set by using synthetic network traffic, this research achieved the higher accuracy as compared to the previous researches.

The second section deals with the modelling of the manufacturing system as queueing system and especially with the connection of the lotsize and the utilization respectively the coefficient of variation of the modelled system. Using a optimization approach for the variation of the lotsizes it is shown that the WIP and the sojourn time can be reduced significantly.
Raising exposure and interactions in French through computer - supported collaborative learning

This case study is part of an action research conducted in a Malaysian public university aiming to develop a computer supported collaborative learning (CSCL) interface for learners of French as a foreign language at the bachelor level. A real task-based CSCL assignment was implemented in a blended learning setting with online activities added to the curriculum without reducing face-to-face contact hours. In line with engaged learning and learner-led theories, 24 learners were asked to collaborate to carry out a complex task that challenges their linguistic and communication skills as well as their organisational aptitude. This study focuses on an analysis of the learners’ perceptions of the CSCL assignment. Questionnaires and guided interviews were carried out to assess the learners’ evaluation of the online support, the relevance of CSCL in a foreign language acquisition and the benefits of real task based assignments. The increased exposure and interactions in the target language and culture resulted in learners’ higher motivation, confidence, and participation. The majority of learners enjoyed this assignment and admitted the benefits of being increasingly challenged. The tutorial was very well received. However, some learners also confided having suffered from too much stress due to zealous team leaders. The learners’ comments and suggestions provided precious feedback on how to improve the implementation of CSCL in the future
FrogPlay as Gamification Tool in Motivating and Engaging School Students: An Analyses Review

In this 21 st century, the use of educational technology has been evolved and civilizing the educational sector. Hence, the Malaysia Ministry of Education (MoE) has been revamped educational curriculum in order to enrich and incorporate information communications and technology (ICT). When integrating ICT into teaching and learning sessions, proved through some educational technology research, it has shown an improvement in the motivation and engagement of students. Furthermore, the full extent capability of educational technology could not be optimized since integrating ICT in education blended with several problems such as misconception about technology use in teaching and learning amongst the teachers, difficulty in accessing to the technology itself and disengagement of students in the classroom during learning sessions. As an alternative to overcome difficulties integrating ICT in education, by integrating games and technology in education has produced offshoots such as game-based learning, serious games and more recently gamification. Gamification refers to the presence of gameful experience to existing systems (example: education) as opposed to creating entirely new or full-fledged games. Gamification paves the way for easier implementation as a tool in motivating and engaging school students. Therefore this paper will discuss the role of FrogPlay as gamification tool in motivating and engaging school students; based on analyses review of several kinds of literature.
Optical Phase Conjugation and All-Optical Demultiplexing using Four-Wave Mixing in Dispersion Shifted Fibers

This thesis deals with two applications of four-wave mixing in optical dispersion-shifted fibers; optical phase conjugation and all-optical switching. The work is a part of an effort to study the upgradability of the existing fiber plant, which is of large economic interest. Present transmission capacities are generally limited by pulse broadening due to chromatic dispersion in the fiber, and by the bandwidths of the electro-optic and opto-electronic interfaces. Optical phase conjugation has been suggested as one technique for compensation of temporal distortion due to linear dispersion and nonlinear effects. It can be implemented via four-wave mixing in an optical fiber, so that the output wave is a true spectrally inverted replica of the input wave. We present experimental and theoretical results on the detrimental effects that undesired nonlinearities in the conjugator will induce, and how they are reduced when a shorter fiber is used. Furthermore, the conversion efficiency and the residual polarization dependence in a polarization-insensitive optical phase-conjugator, using two orthogonal pump-waves, are investigated. We also describe a noise characterization of the conjugator, and calculations of the noise figure indicating 3 dB quantum limit at conversion efficiencies >>100%. The capacity of a transmission system, based on single-mode fibers, is generally much higher than the bandwidth of the electronics at the transmitting and the receiving end. This is sometimes referred to as the "electronic bottleneck", and it can be overcome, e.g. by using several channels on different wavelengths, with a lower bit-rate on each, or with a high bit-rate at one wavelength and all-optical data-switching. In this thesis we present an all-optical demultiplexer with 20 dB inherent amplification, that utilizes four-wave mixing in a dispersion-shifted fiber. We also show how the extinction ratio is deteriorated in a saturated device, and evaluate the influence of variations in zero-dispersion wavelength and parametric noise amplification.
Advances in Pulses Research in Bangladesh Proceedings of the Second National Workshop on Pulses 6-8 Jun 1989 Joydebpur, Bangladesh

Fifty scientists actively engaged in pulses improvement in Bangladesh participated in the second National Workshop on Pulses which was held at the completion of the BARl-lDRC Pulses Project. The representatives of the Pulses Programs from India, Nepal, and Myanmar and scientists from ICRISAT Center (India) also participated. Papers reviewed pulses research done in the eighties on breeding, crop management, crop protection, seed prodution and consumer quality, and regional pulses research links. The workshop recommended expansion of the Pulses Improvement Program In Bangladesh. It was agreed that more genetic variability should be obtained for making rapid progress. The workshop suggested that increased efforts be made to breed for early maturing, disease and pest resistant cultivars and for development of cultural practices for obtaining high stable yields of pulses. The recommendations form a valuable guideline for future research and development of these crops in Bangladesh and other similar regions.
MOLECULAR BEAM EPITAXY: PRINCIPLES AND APPLICATIONS

Universita di Modena e Reggio Emilia, Via Campi 213/A, I-41100 Modena, Italy e-mail: Lucia.Sorba@sci.area. trieste.it 1. Introduction Molecular Beam Epitaxy (MBE) is an Ultra-High-Vacuum (UHV)-based technique for producing high quality epitaxial structures with monolayer (ML) control. Since its introduction in the 1970s as a tool for growing high-purity semiconductor films, MBE has evolved into one of the most widely used techniques for producing epitaxial layers of metals, insulators and superconductors as well, both at the research and the industrial production level. The principle underlying MBE growth is relatively simple: it consists essentially of atoms or clusters of atoms, which are produced by heating up a solid source. They then migrate in an UHV environment and impinge on a hot substrate surface, where they can diffuse and eventually incorporate into the growing film. Despite the conceptual simplicity, a great technological effort is required to produce systems that yield the desired quality in terms of material purity, uniformity and interface control. The choice of MBE and other growth techniques depends on the desired structure and needs. For example, in the case of mass production, MBE suffers from a lower yield, compared to other techniques such as Liquid Phase Epitaxy (LPE) and Metalorganic Vapour Phase Deposition (MOCVD), due to a lower growth rate and wafer capability (currently, GaAs-based MBE production systems are capable of up to 4X6” diameter wafers, compared to 5X10” of MOCVD). MBE, instead, is the proper technique when some particular requirements are needed, such as abruptness and control of interfaces and doping profiles, thanks to the lower growth temperature and growth rate. Besides, the control on the vacuum environment and on the quality of the source materials allows a much higher material purity, compared to non-UHV-based techniques, especially in Al-containing semiconductors for applications in high-mobility, high-speed devices (see Section 5). Finally, the UHV environment allows the use of electron diffraction probes (see Section 2.1), which provide fundamental information on the growth mechanisms. 2. Growth apparatus A schematic drawing of a generic MBE system is presented in Fig. 1. Some basic components can be identified: The vacuum system consists in a stainless-steel growth chamber, UHV-connected to a preparation chamber, where substrates are degassed prior to growth, and a load-lock module for transfer to and from air (not shown). All the components of the growth chamber must be
Development of Green ECC for Sustainable Infrastructure Systems

Over the last decade, enormous strides have been made in creating engineered cementitious composites (ECC) with extreme tensile ductility, on the order of several hundred times that of normal concrete or fiber reinforced concrete (FRC). Current ECC investigations include load carrying structural members in new infrastructure systems, as well as for repair and retrofitting of existing structures. ECC design has been built on the paradigm of the relationships between material microstructures, processing, material properties, and performance. This paradigm has worked very well in creating various versions of ECC that can be processed by self-consolidated casting, spraying, and extrusion. This paper describes preliminary results of an initial attempt at creating Green ECCs – ECCs which maintain the tensile ductility characteristics, but which also incorporate sustainability considerations in the design of these materials for infrastructure applications. Sustainable material design integrates microstructure tailoring with life cycle analysis based on social, environmental, and economic (SEE) indicators. The framework of Green ECC development is described. Some preliminary experimental results of the effect of cement substitution and fiber substitution with industrial by-products on the mechanical properties are reported. It is demonstrated that the concept of green ECC for sustainable infrastructures is feasible, although an extensive amount of research remains ahead.
Importance of coating structure for sheet-fed offset print quality

By varying the pigment composition a wide range of coating structures were produced and evaluated on their printing performance. The paper was produced on a pilot coater and the printing was carried out on a 6-colour sheet-fed offset commercial printing press. Both calendered and uncalendered paper were printed, in total 20 different papers ranging from 10 to 75% in paper gloss. Pore and surface structure had a great impact on printing properties such as print gloss, ink-set rate and rub resistance. Finer pigments and broad particle size distribution resulted in smaller pores. Smaller pores ga ve faster ink setting. Rub resistance was found to pass a minimum at gloss level corresponding to silk paper. Print gloss was determined by surface structure and pore structure. Ink drying, mottling, and surface strength were also investigated.
Charlie: A new robot prototype for improving communication and social skills in children with autism and a new single-point infrared sensor technique for detecting breathing and heart rate remotely

This research delivers a new, interactive game-playing robot named CHARLIE and a novel technique for remotely detecting breathing and heart rate using a single-point, thermal infrared sensor (IR). The robot is equipped with a head and two arms, each with two degrees of freedom, and a camera. We trained a human hands classifier and used this classifier along with a standard face classifier to create two autonomous interactive games: single-player (“Imitate Me, Imitate You”) and two-player (“Pass the Pose”). Further, we developed and implemented a suite of new interactive games in which the robot is teleoperated by remote control. Each of these features has been tested and validated through a field study including eight children diagnosed with autism and speech delays. Results from that study show that significant improvements in speech and social skills can be obtained when using CHARLIE with the methodology described herein. Moreover, gains in communication and social interaction are observed to generalize from child-to-robot to co-present others through the scaffolding of communication skills with the systematic approach developed for the study. Additionally, we present a new IR system that continuously targets the sub-nasal region of the face and measures subtle temperature changes corresponding to breathing and cardiac pulse. This research makes four novel contributions: (1) A low-cost, field-tested robot for use in autism therapy, (2) a suite of interactive robot games, (3) a hand classifier created for performing hand detection during the interactive games, and (4) an IR sensor system which remotely collects temperatures and computes breathing and heart rate. Interactive robot CHARLIE is physically designed to be aesthetically appealing to young children between three and six years of age. The hard, wood and metal robot body is cov-
USABILITY ANALYSIS OF ON-CHIP INDUCTIVE COUPLING MANAGEMENT AND REDUCTION TECHNIQUES

ABSTRACT As very large scale integration (VLSI) technology progresses toward the nanometer range and the operating frequency moves higher into the gigahertz range, parasitic on-chip inductance has become a major concern both from the functionality and performance points of view. The effects of on-chip inductance are strongly associated with higher frequency signal content, denser geometries, and reductions of both resistance and capacitance by copper interconnect and low-K devices. All of these are considered amongst the key practices currently being utilized by designers of state-of-the-art chips to raise the performance levels. A solution to completely address the issue of inductive coupling has not been identified yet. Several point solutions have been proposed to address particular situations. This paper surveys these proposed solutions and discusses their effectiveness in combating the problem. At the end, the paper will present recommendations about the best techniques to be used under given circumstances and the required conditions for the highest benefit from each technique.
Wireless Propagation in Non Line of Sight Urban Areas using Uniform Theory of Diffraction

This paper describes a three-dimensional electromagnetic propagation model for signal power prediction in a non line of sight urban area located in Singapore. The model, which is implemented using the Ohio State NEC-BSC V4.2 basic scattering code and is based on ray theory and uniform theory of diffraction (UTD) takes into account first-order, second order, and third order effects including triple reflections and diffractions. The simplified propagation model of Raffles Place, the central business district of Singapore, uses more than 360 geometrical structures and is compared with data measured at 937.6 MHz along a drive route at the site. The results from the propagation model produced reasonable agreement with the measurements showing that a simplified model using UTD can be used to simulate the gross features of electromagnetic scatter in an urban area. It is shown that use of penetrable dielectric building walls are also necessary for accurate prediction of radio wave propagation in urban areas under non line of sight conditions. It is also found that third order scattering effects can be dominant in non line of sight situations and may be necessary for accurate predictions.
DIGITAL SIGNALING PROCESSOR RESOURCE MANAGEMENT FOR SMALL OFFICE PHONE SYSTEMS

Contemporary small office phone systems are specialized computers that connect a variety of phones within the office and to the local phone company. These systems use digital signaling processors (DSPs) to convert signals from analog to digital and vice-versa. Many different types of applications run on the DSPs and different businesses have varying application needs. Given the systems have limited amounts of DSP resources and growing numbers of applications for a phone system, an administrator needs a way to configure the uses of resources based on their individual business needs. This thesis provides an overview of a system for configuring resources on various types of DSP hardware some of which are removable and have differing tradeoffs between application uses. The system has to be able to change resource allocations while the phone system is running with minimal interruptions to calls. The configuration system needs to be designed to be flexible enough that new applications or DSP hardware could be supported without major changes to code. This thesis presents a system that uses a database-driven model along with algorithms that optimize configuration of DSP hardware given the administrator's individual application needs. v ACKNOWLEDGEMENTS Many thanks to Dr. Alex Dekhtyar for help throughout this process.

Auricular Acupuncture for Preoperative Anxiety - Protocol of Systematic Review and Meta-Analysis of Randomized Controlled Clinical Trials.

Background: Preoperative anxiety causes a profound psychological and physiological reactions, that may lead to a worse postoperative recovery, higher intensity of acute and persistent postsurgical pain and impaired quality of life in the postoperative period. Previous randomized controlled trials (RCTs) suggest that auricular acupuncture (AA) is safe and effective in treatment of preoperative anxiety; a systematic evidence on this topic is missing. Therefore, this protocol was developed following the PRISMA guidelines to adequately evaluate the existing literature regarding the value of AA for the reduction of anxiety in patients in a preoperative setting, compared to other forms of acupuncture or pharmacological or no control interventions and measured with questionnaires regarding anxiety and fear. Methods and analysis: The following databases will be searched: MEDLINE (PubMed), EMBASE, Cochrane Central Register of Controlled Trials (CENTRAL), ISI Web of Science, Scopus Database and Google search. RCTs will be included if an abstract is available in English. Data collection and analysis will be conducted by 2 reviewers independently. Quality and risk assessment of included studies will be done using the Cochrane 5.1. 0 handbook criteria and meta-analysis of effectiveness and symptom scores will be conducted using the statistical software RevMan V.5. 3.Ethics and dissemination: This systematic review will evaluate the efficacy and safety of AA for preoperative anxiety. Since all data used in this systematic review and meta-analysis have been published, this review does not require ethical approval. The results may be published in a peer-reviewed journal or be presented in relevant conferences.Registration number: PROSPERO ID CRD42020184795
Quantum Mechatronics

Mechatronics systems, a macroscopic domain, aim at producing highly efficient engineering platforms, with applications in a variety of industries and situations. On the other hand, quantum technologies, a microscopic domain, are emerging as a promising avenue to speed up computations and perform more efficient sensing. Recently, these two fields have started to merge in a novel area: quantum mechatronics. In this review article, we describe some developments produced so far in this respect, including early steps into quantum robotics, macroscopic actuators via quantum effects, as well as educational initiatives in quantum mechatronics.
