Abstract An essential aspect in the sustainable design of breakwater is the determination of the design wave condition. It is predicted by utilizing severe wave conditions of the past 10 to 20 years. The tourism harbor at eastern Bali, Indonesia, is located where extreme wave condition occurs. Therefore, this research studies the wave height before and after constructing a breakwater in the harbor area. The wave height was simulated using numerical modeling. The methodology was performed by using the coastal modeling software of the SMS-CGWAVE model. The result shows the highest design wave height value of 3.9 m in the direction from the southeast. The design breakwater can reduce wave height up to 0.9 m or a 75.5% reduction. Further study is needed to simulate the extension of breakwater length to meet the criterion design of wave height in the harbor basin.

In this chapter are developed some considerations about the heuristic potentialities of parametric digital modeling as a tool for analyzing and interpreting architectural heritage. Observed that the parametric thinking in architecture could be recognized almost from the origin, new parametric modeling software allows to verify the design criteria of the past. On the basis of previous studies on Baroque vaulted atria, this chapter develops, using parametric modeling tools, a real vocabulary of shapes and their possible combinations, suggested by the architectural literature of the time and the survey of about seventy atria in Turin. This method has been tested on the case study of the lunettes dome in the atrium of Palazzo Carignano.

Sloping Bottom

Determination of a design wave height at a coastal structure requires calculation of a shoaling coefficient or determination of the maximum probable breaking wave height at the point of interest. In shallow water over a sloping bottom, low steepness waves are not accurately predicted by linear shoaling coefficients. Empirical breaking indices are inconsistent with both linear and nonlinear wave theories. Nevertheless, the coastal engineer must select a design wave in order to responsibly design the structure. A graphical procedure is presented herein to relate the equivalent deepwater wave to a breaking wave as it transitions into shoaling water. The procedure provides the coastal engineer with a more consistent understanding of the shoaling process. The results furthermore identify regions of relative depth and steepness where discrepancies arise when using linear shoaling coefficients that may significantly alter engineering design and laboratory studies.

Data Censoring

In a study of extreme waves by the Peak Over Threshold (POT) method, the determination of the threshold of data censoring is an essential step. A wrong choice of the threshold can lead to erroneous results of the wave height design and consequently a bad design of maritime structures such as breakwaters for deep sea ports. In this study, we analyzed the influence of the threshold variation on the results of the hundred-year return period waves, generally considered for the design of maritime structures. The sensitivity study allowed us to confirm that the exponential model is the best probability distribution to describe wave data in two points on the Moroccan Atlantic coast for the wave data period from 1958 to 2019. This study also confirmed that a wrong choice of the statistical distribution and a wrong choice of the threshold lead to significant errors in the estimation of design wave height.

Abstract: The monitoring of the vertical behavior of benchmarks installed in the dam crest of the Governador José Richa hydroelectric power plant (UHGJR) has been performed by the first-order differential leveling method with the use of digital leveling systems which are composed of a digital level and a invar barcode rod. By default, the scales of these instruments are the same, but over time both can change, degrading the observations. In the past, the simultaneous calibration of these systems was not considered in the determination of UHGJR settlements, however, after the development of the first calibration system of digital leveling systems in Brazil, it was possible to investigate the equipment performance as well as to determine a scale factor to be applied to correct the level readings. The results achieved are the systems calibration used in the monitoring of the UHGJR and the calibration certificate application in leveled sections in November 2016. The maximum correction applied to the elevation differences was of the order of nine tenths of millimeters, result attributed to the region observed in the rod, since the deviations obtained in the calibration vary according to the reading position at the rod.

Increasing trends in the arctic sea transport lead to the necessity to determine route specific ice conditions to ensure safe vessel transits. In order to achieve this, the comprehensive understanding of ice conditions from the past should be used to predict future trends for arctic sea ice conditions. This paper presents the development of such ice conditions database with the implementation of a satellite data source, which will become a basis for the determination of route specific ice conditions. A case study is performed in order to show how the database could be used to collect the route specific ice data for statistical analyses.

Megalithic sites, tourist assets in Lahat Regency besides waterfalls, are a wealth of culture in the past that have the potential to be a tourist attraction. The location of megalithic sites scattered in several subdistricts and mostly located outside the settlement becomes an obstacle to be developed as a tourist destination. The purpose of this research is to develop an integrated tourism strategy that composes megalithic sites, natural attractions, artificial attractions, settlements, and the empowerment of local communities. This research combines historical research and case study. The case study is used by observing the location of megalithic sites in several districts in the Lahat Regency. The rapid mapping of potential megalithic sites and tourist objects and developed into two zonings. Community empowerment is conducted by focusing on group discussion (FGD) involving related parties. Megalithic sites are unique, scattered over a wide area, and different geographic conditions make them difficult for tourists to visit. There are several megalithic sites in the settlement, plantation, or rice fields. Local Communities already have an understanding of utilizing homes as homestays. It is concluded that the determination of zonation in Lahat regency can direct the management of the megalithic site as a tourism object according to the site characteristics and the built environment through community empowerment. The first zoning is the location of megalithic sites on Pagaralam as the direction of tourist arrivals with the village of Gunung Kaya in the Jarai sub-district as the node, and the second zonation on Lahat as the direction of tourist arrivals with the village Sinjar Bulan in Gumay Ulu sub-district as the node. Megalithic site management strategy as an integrated tourist attraction is also carried out by utilizing all the existing potential.Situs megalitik adalah warisan budaya di masa lalu yang berpotensi menjadi objek wisata. Lokasi situs megalitik yang tersebar di beberapa kecamatan dan sebagian besar berada di luar pemukiman menjadi kendala untuk dikembangkan sebagai tujuan wisata. Tujuan dari penelitian ini adalah untuk mengembangkan strategi pariwisata terpadu yang menyusun situs megalitik, atraksi alam, atraksi buatan, permukiman, dan pemberdayaan masyarakat lokal. Penelitian menggunakan dua pendekatan, yakni penelitian historis dan studi kasus. Situs megalitik unik, tersebar di wilayah yang luas, dan kondisi geografis yang berbeda membuat mereka sulit dikunjungi wisatawan. Ada beberapa situs megalitik di pemukiman, perkebunan, atau sawah. Masyarakat setempat sudah memiliki pemahaman tentang pemanfaatan rumah sebagai homestay. Disimpulkan bahwa penentuan zonasi di Kabupaten Lahat dapat mengarahkan pengelolaan situs megalitik sebagai objek wisata sesuai dengan karakteristik situs dan lingkungan binaan melalui pemberdayaan masyarakat. Zonasi pertama adalah lokasi situs megalitik di Pagaralam sebagai arah kedatangan wisatawan dengan desa Gunung Kaya di kecamatan Jarai sebagai simpul, dan zonasi kedua di Lahat sebagai arah kedatangan wisatawan dengan desa Sinjar Bulan di kecamatan Gumay Ulu sebagai simpul.

Electron microscopic methods have been applied increasingly during the past fifteen years, to problems in structural molecular biology. Used in conjunction with physical chemical methods and/or Fourier methods of analysis, they constitute powerful tools for determining sizes, shapes and modes of aggregation of biopolymers with molecular weights greater than 50, 000. However, the application of the e.m. to the determination of very fine structure approaching the limit of instrumental resolving power in biological systems has not been productive, due to various difficulties such as the destructive effects of dehydration, damage to the specimen by the electron beam, and lack of adequate and specific contrast. One of the most satisfactory methods for contrasting individual macromolecules involves the deposition of heavy metal vapor upon the specimen. We have investigated this process, and present here what we believe to be the more important considerations for optimizing it. Results of the application of these methods to several biological systems including muscle proteins, fibrinogen, ribosomes and chromatin will be discussed.
