Published: March 2021

Every semester, a new
batch of final year students needs to find a topic and a supervisor to
complete their final year project requirement. The problem with the current approach is that
it is based on first come first serve. So, the pairing between student and supervisor is not
the
optimal ones, i.e. some students may not get their preferred topic or supervisor. Plus, it is also
time consuming for both students and supervisors. The researcher is motivated to solve this
long overdue problem by applying a stable marriage model tha
t is introduced by Gale and
Shapley hence the name Gale
-
Shapley Algorithm. To determine the functionality of this
approach, a system prototype has been constructed and a random dataset is used. The result,
60% of the students get their first choice topics
while the remaining students get their second
or third choice. This is a remarkable outcome considering the time and effort saved compared
to the current process. Therefore, stable marriage model is applicable in solving student

Published: March 2021

Representing any ideas with pictures rather than words is intuitively more appealing because a visual presentation can be more readily understood than that of textual-based. Program visualisation is one of the techniques that can be used in teaching to help users in understanding how programs work. Program visualisation technique is a mental image or a visual representation of an object, scene, person or abstraction that is similar to visual perception. This technique is significant to users because the criteria of source code cannot be physically viewed. It is applicable in the process of writing programs as it helps users to understand their codes better. The purpose of program visualisation is to translate a program into a graphical view to show either the program code, data or control flow. Visualisation technique uses the capability of human visual system to enhance program comprehensibility. Thus, this study uses program visualisation technique to represent program domain in a graphical view to help novices in improving their comprehension. This research aims to support beginners or novice programmers who have been exposed to programming languages by providing effective visualisation technique.
Parametric Study of Fatigue Crack Growth in a Finite Plate
Authors: Ramalho Luís , D. S. G. Campilho Raul , Belinha Jorge , De Castro Paulo M. S. T.
Published: March 2021

Fatigue crack propagation is an undesirable phenomenon that may lead to catastrophic failures in many components and structures, therefore it is important to understand its underlying mechanics. To that effect, systematic parametric studies of fatigue crack propagation laws are interesting to determine how fatigue life varies with the constants that define the mechanical behavior of a given material in a fatigue situation, such as the Paris’ law constants, fracture toughness (Kc) or the stress range ??.

The parametric studies performed in the present work assess the influence of several parameters, assuming that failure occurs when K>Kc, but also when all the material ahead of the crack is yielding. It was found that m and C, the Paris’ law parameters, are the most influential parameters in terms of fatigue life. The present study should help future designers when choosing materials for components or structures subjected to cyclic loads.

In this paper, we study multi-dimensional wave-like equations with variable coefficients within the frame of the fractional calculus using fractional natural decomposition method (FNDM). The considered algorithm is an elegant combination of natural transform and decomposition scheme. Five different cases are considered to illustrate and validate the competence of the projected technique in the present framework. The behaviours of the obtained results have been captured for diverse fractional order. To present the reliability and exactness of the FNDM, the numerical study has been presented. The achieved consequences illuminate that, the projected technique is very effective to analyse and easy to employ to investigate the nature of fractional nonlinear coupled system exemplifying the real-world problems.

PDAM Kota Makassar merupakan perusahaan daerah yang bertugas dalam  pengelolaan dan pemenuhan kebutuhan air bersih bagi masyarakat di kota Makassar. Penyaluran air bersih yang dilakukan PDAM Kota Makassar masih belum mencakup keseluruhan wilayah Kota Makassar,  ini disebabkan karena beberapa hal salah satu diantaranya debit air yang berkurang. Untuk mengatasi hal tersebut pemerintah kota Makassar melalui PDAM, melakukan pendistribusian air dengan cara pengantaran langsung ke rumah warga menggunakan mobil tangki. Proses penyaluran air PDAM mengalami kesulitan untuk menentukan daerah atau warga mana saja yang mendapatkan prioritas pengantaran air bersih, karena armada yang digunakan masih kurang. Mengatasi hal tersebut maka dibuat sebuah Sistem Pendukung Keputusan Pendistribusian Air Bersih, untuk memudahkan prioritas pengantaran air bersih. Metode penelitian melalui empat tahapan yaitu, pengenalan masalah, pengumpulan data, perancangan sistem, dan pengujian sistem, sedangkan metode yang digunakan adalah metode Topsis yang menggunakan 4 kriteria yakni; Peruntukkan, Jarak, Jumlah Kubik yang dipesan, dan Prediksi Jumlah pemakai. Peneliti memilih metode TOPSIS agar penentuan alternatif antara jarak ideal positif dan negatif lebih optimal. Hasil dari penelitian ini merupakan sistem pendukung keputusan pendistribusian air bersih PDAM  yang berbasis web yang memudahkan penentuan prioritas  penyaluran air bersih kepada masyarakat.

 

Abstract

PDAM Makassar City is a regional company assigned to manage the fulfillment of clean water needs for citizens of Makassar City. Currently, the distribution of clean water still has not fully covered the entire area of Makassar City.  The major causes of this situation is a dramatic decrease of the water debit in certain time. To overcome this problem, the government of Makassar city through PDAM, distributes water by direct delivery to the resident's houses using tank trucks.  The process of channeling water from PDAM has difficulty in determining priority areas of delivery due to lack of the fleet. This research consists of  four stages, namely: recognition of problems, data collection, system design, and system testing. While for the algorithm using the TOPSIS method that incorporate four criterias including the allotment, distance, amount of cubic, as well as predicted number of users. The  TOPSIS method is chosen since the determination between the positive and negative ideal distances is more optimal. The results of this study is a web-based decision support system for clean water distribution of PDAM that helps to determine the priority of clean water distribution to the community in Makassar.
A new method to select demulsifiers and optimize dosage at wet crude oil separation facilities

The current practice for crude oil demulsifier selection consists of pre-screening of the best performing demulsifiers followed by field trials to determine the optimum demulsifier dosage. The method of choice for demulsifier ranking is the bottle test. As there is no standard bottle test method, there are different methodologies reported in the literature. In this work, a new approach to bottle test and field trial was described which improved significantly the selection and dosage of the demulsifier. The bottle test was optimized by measuring an accurate mass of demulsifier. This method produces repeatable results. This bottle-test methodology was benchmarked against field trial results performed in oil processing plants. The field trials were also improved to avoid the accumulation effect of demulsifier, when optimizing their dosage. The field data for the optimization of demulsifier dosage was analyzed mathematically; and a graphical method to determine the optimum range is described.

Background:

Aneurysms of the cortical branches of the middle cerebral artery (MCA) are rare. They usually are secondary to traumatic or infectious etiologies and are rarely idiopathic. The specific characteristics of idiopathic aneurysms in such location are not well defined in the literature. The authors report a rare case of a ruptured giant idiopathic cortical MCA aneurysm with review of the available literature on this clinical entity.

Case Description:

A 24-year-old female presented with headache, disturbed level of consciousness, and right-sided weakness. Imaging studies showed a left frontoparietal intracerebral hematoma and a giant saccular aneurysm in the posterior parietal cortical branch of the MCA. The patient had no history of head trauma or active infection; therefore, the aneurysm was considered idiopathic. A microsurgical clipping of the aneurysm with evacuation of the hematoma was performed. There were no surgical complications, and the patient achieved a good outcome modified Rankin Scale of 1 with no neurological deficits.

Conclusion:

Idiopathic aneurysms of the cortical branches of the MCA are rare, and usually present with intraparenchymal hemorrhage due to rupture. There is no clear consensus regarding the optimal management strategy. This case shows that timely management can lead to good outcomes.
Quantum measurements for hidden subgroup problems with optimal sample complexity
Authors: Hayashi M. , Kawachi A. , Kobayashi H.
Published: March 2021

One of the central issues in the hidden subgroup problem is to bound the sample complexity, i.e., the number of identical samples of coset states sufficient and necessary to solve the problem. In this paper, we present general bounds for the sample complexity of the identification and decision versions of the hidden subgroup problem. As a consequence of the bounds, we show that the sample complexity for both of the decision and identification versions is $\Theta(\log|\HH|/\log p)$ for a candidate set $\HH$ of hidden subgroups in the case \REVISE{where the candidate nontrivial subgroups} have the same prime order $p$, which implies that the decision version is at least as hard as the identification version in this case. In particular, it does so for the important \REVISE{cases} such as the dihedral and the symmetric hidden subgroup problems. Moreover, the upper bound of the identification is attained \REVISE{by a variant of the pretty good measurement}. \REVISE{This implies that the concept of the pretty good measurement is quite useful for identification of hidden subgroups over an arbitrary group with optimal sample complexity}.
Scalable, efficient ion-photon coupling with phase Fresnel lenses for large-scale quantum computing
Authors: Streed E.W. , Norton B.G. , Chapman J.J. , Kielpinski D.
Published: March 2021

Efficient ion-photon coupling is an important component for large-scale ion-trap quantum computing. We propose that arrays of phase Fresnel lenses (PFLs) are a favorable optical coupling technology to match with multi-zone ion traps. Both are scalable technologies based on conventional micro-fabrication techniques. The large numerical apertures (NAs) possible with PFLs can reduce the readout time for ion qubits. PFLs also provide good coherent ion-photon coupling by matching a large fraction of an ion's emission pattern to a single optical propagation mode (TEM$_{00}$). To this end we have optically characterized a large numerical aperture phase Fresnel lens (NA=0.64) designed for use at 369.5 nm, the principal fluorescence detection transition for Yb$^+$ ions. A diffraction-limited spot $w_0=350\pm15$ nm ($1/e^2$ waist) with mode quality $M^2= 1.08\pm0.05$ was measured with this PFL. From this we estimate the minimum expected free space coherent ion-photon coupling to be 0.64\%, which is twice the best previous experimental measurement using a conventional multi-element lens. We also evaluate two techniques for improving the entanglement fidelity between the ion state and photon polarization with large numerical aperture lenses.
Estimating Jones and HOMFLY polynomials with one clean qubit
Authors: Jordan S.P. , Wocjan P.
Published: March 2021

The Jones and HOMFLY polynomials are link invariants with close connections to quantum computing. It was recently shown that finding a certain approximation to the Jones polynomial of the trace closure of a braid at the fifth root of unity is a complete problem for the one clean qubit complexity class\cite{Shor_Jordan}. This is the class of problems solvable in polynomial time on a quantum computer acting on an initial state in which one qubit is pure and the rest are maximally mixed. Here we generalize this result by showing that one clean qubit computers can efficiently approximate the Jones and single-variable HOMFLY polynomials of the trace closure of a braid at \emph{any} root of unity.
Properties of local quantum operations with shared entanglement
Authors: Gutoski G.
Published: March 2021

Multi-party local quantum operations with shared quantum entanglement or shared classical randomness are studied. The following facts are established: * There is a ball of local operations with shared randomness lying within the space spanned by the no-signaling operations and centred at the completely noisy channel. * The existence of the ball of local operations with shared randomness is employed to prove that the weak membership problem for local operations with shared entanglement is strongly NP-hard. * Local operations with shared entanglement are characterized in terms of linear functionals that are "completely'' positive on a certain cone K of separable Hermitian operators, under a natural notion of complete positivity appropriate to that cone. Local operations with shared randomness (but not entanglement) are also characterized in terms of linear functionals that are merely positive on that same cone K. * Existing characterizations of no-signaling operations are generalized to the multi-party setting and recast in terms of the Choi-Jamio\l kowski representation for quantum super-operators. It is noted that the standard nonlocal box is an example of a no-signaling operation that is separable, yet cannot be implemented by local operations with shared entanglement.

This note proves that arbitrary local gates together with any entangling bipartite gate V are universal. Previously this was known only when access to both V and V^\dag was given, or when approximate universality was demanded.
