Learning Complex Policy Distribution with CEM Guided Adversarial Hypernetwork
No full textCross-Entropy Method (CEM) is a gradient-free direct policy search method, which has greater stability and is insensitive to hyperparameter tuning. CEM bears similarity to population-based evolutionary methods, but, rather than using a population it uses a distribution over candidate solutions (policies in our case). Usually, a natural exponential family distribution such as multivariate Gaussian is used to parameterize the policy distribution. Using a multivariate Gaussian limits the quality of CEM policies as the search becomes confined to a less representative subspace. We address this drawback by using an adversarially-trained hypernetwork, enabling a richer and complex representation of the policy distribution. To achieve better training stability and faster convergence, we use a multivariate Gaussian CEM policy to guide our adversarial training process. Experiments demonstrate that our approach outperforms state-of-the-art CEM-based methods by 15.8% in terms of rewards while achieving faster convergence. Results also show that our approach is less sensitive to hyper-parameters than other deep-RL methods such as REINFORCE, DDPG and DQN.Interactive Intelligenc

Coilgun Structures
No full textResearch on coilguns at the Center for Electromechanics at the University of Texas at Austin (CEM-UT) has yielded considerable insight into the optimal design of coilgun structures. This research has indicated that the structural requirements are strong functions of launcher classification as well as acceleration mode. As a result, CEM-UT has built and tested the DC coaxial accelerator (DCA) coilgun, which is a multistage pulsed induction launcher that makes extensive use of composite material technology. The author presents analytical techniques (closed-form and numerical) used to make structural design calculations in the DCA launcher. The evolution of the multiturn wound DCA armature design is discussed. In addition, measured plastic deformation of this armature after a high-energy experiment is compared to that predicted by finite element analysisCenter for Electromechanic

tamamlanmıĢtır.This study focuses on Cem Sultan‟s poems written in the tone of friendly
chat included in the book Câm-ı Cem-âyîn by Bayatî. The study aims to
reveal what is unknown about the poet‟s life, personality, poems and his era.
This study is concerned with friendship between Prince Cem (date of death
900/1495) and Hasan Bayatî (date of death 900/1495 in life) which started in
Kaaba, the reason why the book “Câm-ı Cem-âyîn” was written, its
importance and publication. This current study analyses two poems of Cem
Sultan which are not included in his Turkish Collection of Poems, and makes
explorations about Cem Sultan by setting out from these two poems and from
the findings obtained by Ali Emîrî. Câm-ı Cem-âyîn, a short history of Ottoman Turks lineage, is a very important work in that it includes
information on Bayatî‟s and especially Cem Sultan‟s life and personality.
The study consists of introduction, two chapters, conclusion and a chapter
about bibliography. In the introduction part the preface written by Ali Emîrî,
information about the work based on the preface, and about the author is
presented and then information on the form, content and publication of the
book is offered. In Chapter One information about Cem Sultan‟s life is given
based on two different studies, and a lyric poem (gazal) written by Bayatî in
Persian language and a poem written by Cem Sultan in parallel to Bayatî‟s
gazal in Turkish language (nazire gazal) are also analysed in this chapter. In
Chapter Two a historical “tahmisnâme”, which is included in the epilogue of
Câm-ı Cem-âyîn and which is the subject matter of this study is analysed in
terms of form, content, and linguistic and stylistic properties. Having
paraphrased the full text of this important poem- which is in the tone of
friendly chat- with explanatory notes, the book reaches the conclusion and
ends with bibliography giving references

Does strict employment protection discourage job creation? Evidence from Croatia
No full textEmployment protection legislation in Croatia is among the most strict in Europe. Firing is difficult and costly, and flexible forms of employment are limited. Is this apparent rigidity reflected-as one would expect based on standard economic theory-in low labor market dynamics? Is job creation low and hiring limited? Is the job security of insiders achieved at the cost of outsiders not being able to enter thelabor market? The author attempts to answer these questions by examining job flows. If the employment protection legislation is binding, then job and worker turnover should be low. He shows that this is indeed the case. Hiring is limited and the average job tenure is very long in Croatia. Job destruction is low, however job creation is still lower. The result is accumulation of unemployment, in large part due to new labor market entrants not being able to find a job. The high degree of job protection also seems to strengthen the bargaining position of insiders and results in relatively high wages. So, wages in Croatia are higher than among its competitors, even after adjusting for productivity. These high labor costs are likely to contribute to limited job creation in existing firms, but also are likely to discourage the entry of-and thus job creation in-new firms. The author presents evidence that firm growth has been indeed limited in Croatia, contributing to the low employment level. The author examines other potential causes of high unemployment in Croatia (the unemployment benefit system, labor taxation, the wage structure, and skill and spatial mismatches). He argues that they do not play a substantial part in accounting for poor labor market outcomes in Croatia. The author concludes that the stringent employment protection legislation is the key labor market institution behind low job creation and high unemployment. Based on this he recommends specific measures aimed at liberalizing the labor market to foster job creation and employment.Labor Management and Relations,Labor Policies,Labor Markets,Environmental Economics&Policies,Trade Finance and Investment,Labor Markets,Labor Management and Relations,Labor Standards,Banks&Banking Reform,Environmental Economics&Policies

Taş dolgu dalgakıran müzvarının liman tarafındaki dalga yükleri üzerine bir araştırma
No full textIt is well-known that head sections of the rubble mound breakwaters are more critical than trunk sections in terms of stability. The common practice is to use heavier armor layer units at the head sections of rubble mound breakwaters, especially at the lee-side of the head sections. However, the relation between the wave parameters and hydrodynamic loading at the lee-side of the head section has not been completely investigated.
In the scope of this study, physical model experiments were conducted to observe the relation between the wave parameters and hydrodynamic loading at the lee-side of the head section of a rubble mound breakwater constructed using antifer units. The experiments were carried out at the Coastal and Ocean Engineering Laboratory of the METU Civil Engineering Department. The armor layer slope of the tested physical model was 1:1.5, and antifer units were placed on both the head and trunk sections of the breakwater. In the experiments, 8 different water depths, 13 different wave periods, and a single wave steepness value of 0.045 were considered. During the experiments, pressure measurements on the top face of a single antifer unit at the lee-side of the head section were carried out in addition to water surface elevation and particle velocity measurements at different locations along the wave flume and around the cross-section.
According to the results, during the passage of a single wave, hydrodynamic loading on a single antifer unit changes remarkably depending on the presence and location of wave-breaking. It is observed that the pressure signal on the top face of the unit takes a double-peaked form rather than single-peaked with strong negative dynamic pressure values when the plunger breaks at an average circumferential distance of 1.08 unit width offshore and vertical distance of 0.61 unit width above. Furthermore, velocities significantly increase closer to the lee-side of the head section up to three times the undisturbed values.Taş dolgu dalgakıranların müzvar kısmının stabilite açısından gövde kısmına göre daha kritik olduğu bilinmektedir. Yaygın olan uygulama, taş dolgu dalgakıranların müzvar kısmında, özellikle müzvar kısmının liman tarafında daha ağır koruyucu tabaka elemanlarının kullanılmasıdır. Ancak müzvar kısmının liman tarafında dalga parametreleri ile hidrodinamik yükleme arasındaki ilişki tam olarak araştırılmamıştır.
Bu çalışmanın kapsamında, antifer birimler kullanılarak inşa edilen bir taş dolgu dalgakıranın müzvar kısmının liman tarafında dalga parametreleri ve hidrodinamik yükleme arasındaki ilişkiyi gözlemlemek için deneysel bir çalışma yapılmıştır. Deneyler ODTÜ İnşaat Mühendisliği Bölümü Kıyı ve Deniz Mühendisliği Laboratuvarı’nda gerçekleştirilmiştir. Test edilen fiziksel modelin koruma tabakası eğimi 1:1,5 olup, antifer birimleri dalgakıranının hem müzvar hem de gövde kısımlarına yerleştirilmiştir. Deneylerde 8 farklı su derinliği, 13 farklı dalga periyodu ve 0,045’lik tek bir dalga dikliği değeri dikkate alınmıştır. Deneyler sırasında, dalga kanalı boyunca ve kesit çevresinde farklı noktalarda su yüzeyi yüksekliği ve parçacık hızı ölçümlerine ek olarak, müzvar kısmının liman tarafında tek bir antifer biriminin üst yüzeyinde basınç ölçümleri gerçekleştirilmiştir.
Sonuçlara göre, tek bir dalganın geçişi sırasında, bir antifer biriminin üzerindeki hidrodinamik yükleme, dalga kırılmasının olmasına ve konumuna bağlı olarak önemli ölçüde değişiklik göstermektedir. Dalganın sensöre ortalama 1,08 birim genişlikte çevresel mesafede ve ortalama 0,61 birim genişlikte düşey mesafede kırılması durumunda, antifer ünitesi üzerinde okunan basınç sinyalinin güçlü negatif dinamik basınç değerleri ile tek tepeli yerine çift tepeli bir şekil aldığı görülmektedir. Ayrıca, hızlar müzvar kısmının liman tarafına yaklaştıkça, yapıdan uzaktaki hız değerlerinin üç katına kadar önemli ölçüde artmaktadır.M.S. - Master of Scienc
