The purpose of this paper is to develop a lane detection analysis algorithm by Hough transform and histogram shapes, which can effectively detect the lane markers in various lane road conditions, in driving system for drivers.
Step 1: receiving image: the developed system is able to acquire images from video files. Step 2: splitting image: the system analyzes the splitting process of video file. Step 3: cropping image: specifying the area of interest using crop tool. Step 4: image enhancement: the system conducts the frame to convert RGB color image into grayscale image. Step 5: converting grayscale image to binary image. Step 6: segmenting and removing objects: using the opening morphological operations. Step 7: defining the analyzed area within the image using the Hough transform. Step 8: computing Houghline transform: the system operates the defined segment to analyze the Houghline transform.
This paper presents the useful solution for lane detection by analyzing histogram shapes and Hough transform algorithms through digital image processing. The method has tested on video sequences filmed by using a webcam camera to record the road as a video file in a form of avi. The experimental results show the combination of two algorithms to compare the similarities and differences between histogram and Hough transform algorithm for better lane detection results. The performance of the Hough transform is better than the histogram shapes.
This paper proposed two algorithms by comparing the similarities and differences between histogram shapes and Hough transform algorithm. The concept of this paper is to analyze between algorithms, provide a process of lane detection and search for the algorithm that has the better lane detection results.

THE Paris Aero Show—the oldest in the world, since it was first held, though unofficially, in December, 1908—took place this year from November 28 to December 14, in its usual quarters, the Grand Palais des Champs‐Elysées. This Salon, the twelfth of the series—as the first official one dates from 1909, there being, of course, a gap from 1914–1918, and after 1922 it laving been decided to hold it in alternate years—is, as usual, conducted by the “Chambre Syndicale des Industries Aéronautiques,” of which M. Fernand Lioré, the well‐known aeroplane and flying‐boat manufacturer, is the present President, M. André Granet being Commissaire‐Général.

A report on this subject has recently been issued by the Local Government Board. It owes its origin to the interest—unfortunately brief—that was aroused some two years ago, when certain allegations were made concerning the methods in vogue on the other side of the Atlantic for, the preparation of meat products intended to be placed on the English market, and has been drawn up by Dr. A. W. J. MACFADDEN. The report is based on the results obtained by Public Analysts throughout the country, who, in the performance of their official duties, were called upon to examine various samples of canned meat sent out by the United States packing houses; on certain statements made by trade representatives to Dr. MACFADDEN; and, finally, on the results of some analyses of canned meats made by Mr. ELLIS RICHARDS, F.I.C., at the request of the Board. The figures must be regarded as representative of the state of affairs then and now. By far the greater quantity of canned meat that reaches this country and is consumed therein is imported from the United States, and hence, almost of necessity, any criticisms that are made regarding this part of our food supply resolve themselves into criticisms of the Federal Meat Inspection law of the United States and the way in which it is applied by the officials there. The conclusion that Dr. MACFADDEN draws as to the efficacy of this law so far as it regards ourselves is one that was expressed in this journal in May last. He observes that “our position, so far as safeguards provided by American law are concerned, is apparently much as it was before the enactments came into force,” that “so far as the use of preservatives is concerned, the new law has not affected the conditions under which the canned meat trade has been conducted with this country in past years,” and that “the onus of protecting their inhabitants in this respect continues to rest, in the first place, with the Governments of the foreign countries themselves.” The first two statements are sufficiently damning, and the corollary is, of course, obvious. The difficulties must be tackled from this side, but the entire absence, up to the present, of all official standards renders the task of the Public Analyst and the other municipal officials who are jointly concerned with him as regards the health of the districts with which they are connected, a most difficult one, and the business of the unscrupulous “poisoner for dividends,” to use an American phrase, correspondingly easy. We go a little farther than Dr. MACFADDEN, and say that the new law does not protect us even with regard to the general wholesomeness of these products. As late as January last the Inspecting Officer of the Manchester Port Sanitary Authority had occasion to draw attention to the unsatisfactory nature of certain canned goods that were imported direct from America. The examination of a consignment of 1,200 six‐pound tins of canned meat showed that 157 tins were blown, and that 156 tins were of doubtful quality. It follows that in this single instance 1,800 pounds of garbage were exported to this country from the United States, the new law notwithstanding.

SEPTEMBER, by a traditional impulse, has always represented to some minds the beginning of the most active period in the library year. This year the month that sees the close of the holiday season, the shortening day and lengthening evening, holds fairer promises and greater difficulties than any in the past six years or perhaps in the past twenty‐five. It sees large programmes in prospect but many fences to be surmounted and, if the physicists are right, the beginning of a new era. It is doubtful if, in so short a space of time as that which has elapsed since we last wrote, so many important events have occurred. The entirely new political alignment may have its effects on our post‐war policy. We hope the library will never again be the protege of a political party because that means that it becomes thereby the target of the opposition—as was the case when in London a change of party in local government brought about the wreck for a generation of at least one library service which had the misfortune to have been initiated by the other party. We have however, no immediate apprehensions about public libraries in present circumstances.

One of the most challenging problems facing the package designer today is how to predict electrical performance before committing a design to fabrication. One means of accomplishing this task is to employ computer‐aided design (CAD) tools that analyse performance from simulations done on models derived from the physical package structures. These models, when combined with the chip models, allow interactive simulation and timing analysis of an entire multilayer package. This paper describes a CAD approach for evaluating interconnect performance within multilayer package structures and presents several examples to show how the approach is applied.

In this chapter, the authors consider the role of time for research in occupational stress and well-being. First, temporal issues in studying occupational health longitudinally, focusing in particular on the role of time lags and their implications for observed results (e.g., effect detectability), analyses (e.g., handling unequal durations between measurement occasions), and interpretation (e.g., result generalizability, theoretical revision) were discussed. Then, time-based assumptions when modeling lagged effects in occupational health research, providing a focused review of how research has handled (or ignored) these assumptions in the past, and the relative benefits and drawbacks of these approaches were discussed. Finally, recommendations for readers, an accessible tutorial (including example data and code), and discussion of a new structural equation modeling technique, continuous time structural equation modeling, that can “handle” time in longitudinal studies of occupational health were provided.

Flooding is a frequent problem in the United Kingdom, with 1.8 million people living in homes that are likely to flood at least once in 75 years (Sayers, Horritt, Penning-Rowsell, & McKenzie, 2015). In 2015, the River Am burst its banks, resulting in up to 1 metre of flooding in Ambridge and causing significant damage and disruption to the village. A ‘4Ps’ approach is proposed to predict, prevent, protect from and prepare for flooding. Applying this model to evidence from Ambridge allows strategies for a flood resilient community to be explored.
