Published: February 2020

Delme işlemi, geleneksel imalat yöntemleri arasında talaşlı imalat işlemlerinin yaklaşık olarak %33’ünü oluşturmaktadır. Bu işleminin imalat alanındaki önemine rağmen matkabın uç açısı, fener mili devri, ilerleme miktarı ve delinen malzemenin özellikleri gibi birçok parametre delik delme işlemini etkilemektedir. Bu amaçla gerçekleştirilen bu deneysel çalışmada, farklı uç açılarına sahip matkaplar ile delme işlemi esnasında meydana gelen tepki kuvveleri Yüzey Yanıt Yöntemi (YYY) ile analiz edilmiştir. İtme kuvvetlerini meydana getiren üç farklı fener mili devir sayısı, ilerleme miktarı ve matkap uç açıları seçilerek toplam 27 adet deney gerçekleştirilmiştir. Deney parametrelerine bağlı olarak en iyi tepki kuvvetini tahmin etmek için oluşturulan YYY üç seviyeli ve üç faktörlü Box-Behnken tasarım yöntemi dikkate alınarak oluşturulmuştur. Deney sonuçlarından elde edilen tepki kuvvetleri, birinci dereceden ve ikinci dereceden matematiksel modeller oluşturulmuştur. Elde edilen bu modellerin etkinliği ANOVA testi yapılarak parametrelerin etkinliği araştırılmıştır. Sonuç olarak parametrelerin tepki kuvvetleri üzerindeki etkinliği karşılaştırılmış ve en etkili parametrenin ilerleme miktarı olduğu tespit edilmiştir. Ayrıca rastgele seçilen deney verileri ile YYY ile oluşturulan modeller karşılaştırılmış 0,964 R2 değeri elde edilmiştir. YYY ile delme işleminde meydana gelen tepki kuvvetlerinin değerleri çok küçük hata oranlarında tahmin edebildiği belirlenmiştir.

Senkron Relüktans Motor (SynRM) sağlam ve basit yapı, düşük maliyetli üretim, birim hacim başına yüksek moment imkânı, kontrol basitliği, alan zayıflatma kabiliyeti ve rotor sargılarının bulunmaması nedeniyle azalan kayıplar gibi birçok avantaja sahiptir. Bu yüzden, bu motorlar çok sayıda endüstriyel ve otomotiv uygulamalar için ilgi çekici hale gelmeye başlamıştır. Düşük çap ve düşük gerilime sahip bir motor ile yüksek moment üretilmesi oldukça zordur. Bu makalede; fotovoltaik (PV) panellerin ürettiği düşük gerilim seviyesiyle çalışabilen bir SynRM tasarımı amaçlanmıştır. Bu motor iyi bir dinamiğe sahip, yüksek kalkış momentli ve yüksek verimli bir motor olarak tasarlanmıştır. Motor, akım başına düşen maksimum moment (MTPA) kontrol algoritması ile kontrol edilmiştir. Ayrıca panellerden maksimum güç elde edilebilmesi için Maksimum Güç Noktası İzleme (MPPT) algoritması kullanılmıştır. Bu algoritma motorun hız-referans bilgisini otomatik olarak değiştirerek sistemin maksimum verimde çalışmasını sağlamıştır. Bu çalışmada, geleneksek sistemlere göre daha verimli, daha kompakt ve kullanım kolaylığı sağlayan bir sistem elde edilmiştir.

Relevance of Law Consumer Protection on Aircraft Post Master Flight Agent
Authors: Rasyid Fitri Pratiwi
Published: February 2020

At the time of the accident on the Lion Air flight JT 610, there were many ideas to close the flight operating permit. In fact, if reviewed further, for whatever reason, in some "corners", there are other rights that have not even received legal certainty about their protection. One of them is about airline ticket agents. Basically, according to the Consumer Protection Act, protection is not only given to consumers but businesses are also included in carrying out their trading activities. Business actors reach up to the airline agents. Moreover, before having a ticket sales permit, the agent must make a deposit to the airline ticket being sold. However, the protection that should be given in the laws and regulations does not explain the airline's obligation to return deposits to travel agents, who are likely to suffer fatal losses.

This paper investigates the impact of skewed piers and their geometrical shape on the scouring. A non-linear equation estimating scour depths around skewed piers (i.e. Piers Scour Calculator PSC) is established experimentally. The rectangular, semicircle and curvilinear piers are investigated. PSC Eq. gives reasonable values compared to formulas of Froechlich (1988), Chitale (1962), Ahmad (1962) and Inglis-Poona (1949). RSQ values equal 92.5%, 83.5% of the training and validating data, respectively. PSC results are convenient with measurements compared to equations of (Richardson & Davis, 2001) and (Melville & Sutherland, 1988). The experimental results showed that values of the scouring parameter increase by 200%, 270% and 238% for the rectangular, the semicircle, and the curvilinear piers, respectively as the skewed angle increases from 0o to 16.7o. Two empirical equations presenting flow angles and shape factors are developed.

In this paper the influence of geometry on the stability of a functionally graded material rotating beam is reported. The equation of motion is formulated using Hamilton’s principle in association with finite element analyses. Floquet’s theory was used for establishing the stability boundaries. The properties of functionally graded ordinary (FGO) and functionally graded sandwich (FGSW) beams under consideration are assumed to be graded following either power law or exponential law across the thickness of the beam. The effect of geometry in terms of slenderness parameter on the dynamic stability of both FGO & FGSW beams have been investigated. The increase in slenderness parameter enhances the stability of both the FGO and FGSW beams. Further it has been observed that exponential distribution of properties ensures better stability compared to power law distribution of properties.

The use of precast concrete structural systems in civil engineering industry in Indonesia will still increase due to the needs of buildings and infrastructure for social and economic development continuously increase from the year to year. In spite of the use of sand accompanied with its suitable sludge content has been widely used as one of the important raw materials for fabricating a precast concrete, the availability of low cost method to obtain a good quality of sand with its sludge content of less than 5% is difficult to find in many regions in the country. The aim of this study was to assess the performance of four cylindrical concrete specimen (CCS) samples by conducting the experiments of testing the natural sand with its high sludge content of 12.7% with using the different ordinary Portland cement (OPC) compositions of 2.5, 5.0, 7.5 and 10.0% and the super-plasticizer of polycarboxylate ether. Two CCS samples of the same composition (1) using the washed sand with its sludge content of 3.7% and (2) without addition of OPC were used as control. The results of compressive strength and slump test verified that the addition of OPC at least by 2.5% into concrete slurry to ensure optimal performance of the CCS samples can be recommended using the natural sand accompanied with its sludge content of 12.7%. This study concluded that the use of local natural sand with its high sludge content as long as the other material compositions used properly could be safe in the fabrication of precast concrete structure for the future civil engineering applications.

Durian timber grows well in the Gunungpati area, although its use is still limited to the needs of light construction. Lamination (glulam) is a combination of one or more kinds of materials and the materials are made into relatively thin layers glued together to form a larger dimension. Timber engineering experiment was conducted by creating a laminated beam made of Durian and coconut timber, with a composition of coconut - Durian – coconut. The purpose of this study was to determine the bending strength of a composition of coconut – durian – coconut laminated beam in strengthening the weak side of the durian timber. Coconut timber was used to reinforce durian timber because the weight of coconut timber is relatively larger compared to Durian timber. Durian laminated beam with coconut timber reinforcement on the top and bottom can be used as an alternative material to improve the bending strength durian timber. Lamination technology was able to increase the bending strength of Durian timber with laminated beams by 12.6% from the average bending strength of 36.68 MPa durian timber, laminated beams into bending strength of 41.30 MPa.

Therefore, it’s important to obtain the data of strength properties from the structural size specimen as its represent the real behavior of the timber even though the timber strength might be reduce due to the nature of the timber characteristics. This paper reports the investigation on the bending strength properties of keruing and light red meranti from the Malaysian tropical hardwood species in structural size in accordance with EN408. The characteristic values of bending strength, mean modulus, and density are 47.63 N/mm2, 19440.3N/mm2 and 603.38kg/m3, respectively for keruing and 23.05N/mm2, 12182.19 N/mm2 and 302.39kg/m3 respectively for light red meranti. At this moment Keruing can be group in strength class D40 and light red meranti in class D25. These results were different from BS 5268 where Keruing is grouped as D50 and light red meranti as C22 in MS 544 Part 2.

Speech enhancement has been a major challenge in the field of Signal processing. The process of filtering the noise component from the speech signal has achieved many milestones since the early 20th century. Beside many theories Linear prediction coding is one of the best methods for speech, audio signal processing which uses the algorithm of predicting the current estimates based on the past states of an LTI system. Linear prediction is usually used in Speech recognition, Speech enhancement. One of such Kalman filter was introduced and described in 1960 by Rudolf Kalman, which uses the concept of linear quadratic estimation. Kalman filtering is effectively being used in the practical applications like navigation of ships or aircraft, designing motion planning algorithms, in communication area. Kalman filters use the autoregression model of speech for the recursive equations of Kalman filter used in state space model of filter for state estimation. In this paper, we have used Kalman filter to eliminate the pink noise from the corrupted speech signal. Pink noise is very common in electronic devices and occurs in almost all devices. The Speech corrupted with pink noise has been obtained from SpEAR database. We have used MATLAB software for the simulation purpose. Finally, Spectrograms of signals are plotted for a better visual understanding of filtered results.

The portability of power for human health monitoring is considered a challenge for years to come and the recent development in wearable devices has encouraged this research area. This paper develops a composite energy harvesting paradigm that combines piezoelectricity and electromechanical energy production to energize the storage batteries powering wearable devices. A composite mathematical model that combines the piezoelectric process along with the electromechanical process comprising the piston action is developed using MatlabTM. The piezoelectric power is considered to be generated from the pressure created by human weight on it while walking and electromechanical power generated from the limb movement of the human being. The energy thus harvested from both these inputs are consolidated and fed to charge the batteries that feed the wearable sensors. The Lithium-Ion battery of 1.2V rated voltage is charged using the power generated from the mathematical models of both the piezoelectric and electromechanical power generation. The energy generated is found to be satisfactorily charging the battery.

In MANET usually nodes interact with each other either directly or by relaying nodes depending on whether nodes present are in vicinity of each other or not respectively. There are different routing protocols which work on the principle either of demand or not. AODV is a reactive routing protocol which performs on the strategy of shortest hop in its vicinity. Sometimes there is a route failure in network then some message is sent to the node if reply is not received with in time frame then for sure path is broken. So it is wastage of time and energy of all the participating nodes. Main reason behind the node failure is the sustaining energy of the participating nodes in the communication. Since nodes which have very less energy gets consumed when these try to send either data or reply to and from the nodes. Sometimes a node has minimum energy to send data. As soon as it sends data it is switched off and does not send delivery successful reply to the originating network. So in this case network thinks path is broken so message is again sent to another path. So here it again there is loss of energy of other communicating node and also wastage of time to send data to nodes. In this research work, an energy and time efficient approach will be proposed which will save time as well as energy of remaining nodes which further utilizes all the known linked paths simultaneously for transmitting data with the help of AODV routing protocol. Different simulation parameters are used to check the accuracy of approach. Simulation is performed on NS-3. There will be 50 to 100 nodes in the topology. Performance metrics like throughput, energy deviation, packet lost, packet delivery ratio and other will be used for performance checking with respect to standard AODV routing protocol. This research work provides the improvements to the existing algorithms of communication among network nodes in mobile ad-hoc networks (MANET) to obtain better results.

The Internet of Things is altering social lives by associating regular items together. For instance, in a market or stores, all things can be associated with one another, framing a brilliant shopping framework In such system (Internet of Things) IoT framework, a cheap RFID label can be connected to every single item which, when placed into a smart shopping cart, can be automatically read by a cart equipped with an RFID reader. As a result, billing can be conducted from the shopping cart itself, keeping customers from holding up in a long line at checkout point. Alternatively, smart shelving, fitted with RFID readers, can be connected to this smart shopping network and can track stock, perhaps also updating a central server. Extra benefit of this kind of system is that list supervision becomes much easier, as every items can be automatically read by an RFID reader as an alternative of physically look over. To approve the plausibility of such a framework, in this work we distinguish the structure prerequisites of a brilliant shopping framework, fabricate a model framework to test usefulness, and plan a safe correspondence convention to make the framework handy. To the best of our capability, this is the first time that importance is being given to a smart shopping network with safeguards.

Speech is a vocal communication through which we achieve the information about speaker, language, message etc. Speaking is the process of converting discrete phonemes into continuous acoustic signal. Speech carries linguistic information that is associated with emotions, along with vocal information, which can be extracted by speech processing methods. In this paper, we basically analyse on prosodic features of different emotional speech in Assamese language for identify the comparison between male and female speakers who linguistically react differently in the same situations. We also apply statistical paired t-Test on prosodic features for showing the significant difference between male and female speech in different emotions.

Currently due to massive use of internet there is need of huge amount of bandwidth. The utilization of bandwidth can be managed up with optical burst switched networks. These networks cannot provide good QoS due to problems like wavelength contention and congestion problem. Also it is not necessary that contention in a network leads to congestion. It can be due to nodes behavior which affects the flow of traffic from source to destination. Hence there is a need to classify the traffic through the node at correct juncture to avoid congestion. This can be achieved using machine learning techniques. In this paper, support vector machine, AdaBoost classifier and Bagging classifier are evaluated .Experimental work is carried on Optical Burst Switched network dataset using 22 attributes which is available on UCI repository. The results show that bagging classifier performed better with accuracy of 95% in classifying the nodes behavior.
